The problem was one which had arisen as long ago as Old Earth's Roman Empire: when power depends on "bread and circuses," those in power are compelled to provide ever greater largess if they wish to remain in power. In effect, the politicos required a bottomless and ever-filled public trough to pay off the Dolists and provide the graft and corruption to support the lives to which they themselves had become accustomed, and after almost two centuries of increasingly serious self-inflicted wounds, not even the once-robust Havenite economy could support that burden. It became apparent to the political managers that the entire edifice was in trouble: tax revenues had not matched expenditures in over 143 T-years; R&D was faltering as an increasingly politicized (and hence ineffectual) educational system purveyed the pseudo-scientific mumbo-jumbo of collectivist economic theory rather than sound scientific training; and the decreasing numbers of truly capable industrial and technical managers produced by the system were increasingly lured to other star systems whose economies allowed them to use their talents and enjoy the benefits thereof. The "Technical Conservation Act" of 1778, which revoked emigration visas for all research and production engineers by nationalizing their expertise "as a resource of the Republic," was intended to put a stop to that, but it could not reverse the fatal trends.
Real economic growth had stopped—indeed, the economy was contracting—but ever higher Basic Living Stipend payments were politically inescapable, and the stagflation which had resulted was becoming a self-sustaining reaction. In 1771 pd, a highly classified economic report to the House of Legislators predicted that by the year 1870 the entire economy would collapse in a disaster which would make Old Earth's Great Depression and the Economic Winter of 252 pd look like mild recessions. The Chiefs of Staff, apprised of the degree of collapse to be anticipated, warned that it would precipitate pitched warfare in the streets as Haven's citizens fought for food for their families, for Haven had long since attained a population which could not feed itself without imports, and imports could not be paid for with a negative balance of trade.
The government saw only two ways out: to bite the bullet, end deficit spending, abolish the BLS, and hope to weather the resultant catastrophic reorganization, or to find some other source of income to shore up the budget. The possibility of admitting they could no longer pay the interest on Haven's mortgaged future was too much for them to stomach, which meant only the second solution was a real possibility, but there was no more money to be squeezed out of the economy. A panicked group of legislators suggested draconian "soak the rich" schemes, but the majority recognized that any such panacea would be purely cosmetic. Aside from their own hidden assets, the wealthy represented less than 0.5% of the total population, and the totally confiscatory taxes proposed would provide only a temporary reprieve . . . and eliminate both future private investment and the highest tax brackets (already taxed at 92% on personal income and 75% on investment income) as a long-term revenue source. A self-sustaining tax base could be produced only by a strong middle class, and the middle class had been systematically destroyed; what remained of it was far too small to sustain the government's current rate of expenditure and had been for almost a century.
That left only one possible way to find the needed revenue, and the government, with the cooperation of the Quorum, prepared to seize it under the so-called "DuQuesne Plan."
The first step was a "Constitutional Convention" which radically rewrote the Havenite Constitution. While maintaining a facade of democracy, the new constitution, by redefining eligibility requirements and office qualifications and giving the House of Legislators the right to refuse to seat even a legally elected representative if the House found him or her "personally unfit for public office," created a legislative dictatorship with hereditary membership. (It was not a strictly parent-to-child inheritance but rather a codification of the "adoption" process which had become the normal career route for Havenite politicians over the past century; true dynasties came later.) The second step was not to limit deficit spending but to increase it, this time with the enthusiastic support of the military, which underwent the greatest peacetime expansion in Havenite history. And the third step, launched in 1846 pd, was to acquire additional revenue from a totally new source: military conquest.
The initial attacks were almost totally unopposed. The quadrant was so accustomed to the idea that Haven represented the ideal to which all humanity aspired that its steady collapse had been sadly underestimated. Haven's problems were known, but their severity was misjudged, and the consensus was that all of them could be solved if Haven would only put its house in order. Indeed, the majority of Haven's neighbors felt that Haven was on the right track but had simply gotten temporarily out of control, and many of them were in the early stages of the same process in a sort of lemming-like emulation of disaster. The sudden expansion of the Havenite military caused some concern, but those who suggested that long-friendly Haven contemplated hostile action were viewed as hysterical alarmists. Besides, the quadrant's other systems found their own economies were becoming increasingly strapped, and warships and troops cost money which was required for their own welfare programs.
The result was a turkey shoot for the Peoples' Navy. Between 1846 and 1900 pd, a period of barely more than fifty years, the People's Republic of Haven had conquered every star system within a hundred light-years of it, incorporating them by force into a new, interstellar PRH ruled by the now openly hereditary "legislature" of the Haven System.
Unfortunately for the Legislaturalists, they soon discovered that conquest was not the solution they had hoped. True, they could loot the economies of conquered worlds, but unless they wanted servile insurrection, there was a limit to how badly they could wreck their subject economies. Worse, the military machine required to conquer and then police their new empire cost even more than they had anticipated, particularly as their alarmed and (so far) unconquered neighbors began to arm in reply. Despite all efforts, their budgets remained stubbornly in the deficit column; they simply could not pay for both their military and the support of their subsidized population out of available resources. There was an appearance of prosperity on the home front, but those in informed positions knew that it was only an appearance. In short, the "Republic" had only two options: continue to expand, or collapse.
And so, in 1900 pd, the People's Republic had no choice but to look for fresh fields to conquer . . . and found, directly in its path, between it and the additional worlds it had to have, a small but wealthy star system known as the Star Kingdom of Manticore.
