Americans now have to climb out of two deep holes: as debt-loaded consumers, whose personal wealth sank along with housing and stock prices; and as taxpayers, whose government debt has almost doubled in the last two years alone, just as costs tied to benefits for retiring baby boomers are set to explode.
The competing demands could deepen political battles over the size and role of the government, the trade-offs between taxes and spending, the choices between helping older generations versus younger ones, and the bottom-line questions about who should ultimately shoulder the burden.
