Actually, it's not a miracle, but instead common sense conservatism instituted by that mean villain Governor Scott Walker. Liberalism is a complete failure. The states in the worst shape are all run by Democrats.

Wisconsin’s Economic Miracle: Goes From $3 Billion Deficit To $300 Million Budget Surplus Thanks To GOP Gov. Scott Walker…
"(PJM) — 'Over the past six months, Wisconsin has been nothing short of a miracle. Newly elected Governor Scott Walker and the Republicans in the majority in Madison got just about everything they wanted during the past legislative session, and a state facing a projected $3 billion budget shortfall with no end in sight now has a projected $300 million budget surplus. The amazing successes in Wisconsin have emboldened the legislatures and political leaders of other states, who have seen the wonders resulting from a little political backbone and fiscal common sense.
After being held hostage by 14 AWOL Democrat senators, Walker succeeded in passing his budget repair bill, “Act 10,” which instantly fixed the $137 million deficit by requiring public employees to contribute just a little bit toward their pensions and health care, and by limiting their ability to collectively bargain. Wisconsin also ended the ludicrous automatic pay and benefit increases for public employee unions each budget year — closing a cash sinkhole which is eating states like California and Illinois alive. Last month the Wisconsin legislature passed its biennial budget, which Governor Walker promptly signed in a no-frills ceremony.
The repeal of much of Wisconsin’s collective bargaining law has already improved the quality and lowered the cost of Wisconsin government exponentially. There are approximately 275,000 government employees in the state of Wisconsin. About 72,000 such employees work for the state, 38,000 for cities and villages, 48,000 for counties, 10,500 (full time equivalent) for technical colleges, and 105,229 for schools.'
