For years, many conservatives advocated a “starve the beast” approach to limiting government. They supported any tax cut, of any size, at any time, for any purpose, assuming that, deprived of revenue, government spending would stop growing. But spending continued, and government borrowing encouraged government’s growth by making big government cheap: People were given $1 worth of government but were charged less than that, the balance being shifted, through debt, to future generations. In 2003, Republicans fattened the beast with the Medicare prescription drug benefit (Cooper opposed it), which added almost $8 trillion in the present value of benefits scheduled, but unfunded, over the next 75 years.

Liberalism’s signature achievement — the welfare state’s entitlement buffet — will, unless radically reduced, starve government of resources needed for everything on liberalism’s agenda for people not elderly. Conservatives want government limited, but not this way.
