"The government's chief asset—in fact, pretty much its only asset—is its ability to tax people, now and in the future. The taxpayers are the government's ATM. Make a withdrawal today, and there's less available tomorrow.
Now the ability to tax is a pretty huge asset and the government has not (yet!) come close to depleting it. In that sense, there's a lot of money in the bank. But no matter how much you've got in the bank, a policy of ever-increasing withdrawals is nothing at all like a decision to earn more income. It's important to get the analogy right. And it's clear from the blogs and the op-ed pages that not everybody gets this.
Instead, the notion persists that an extra trillion in federal spending can be converted from "irresponsible'' to "responsible'' as long as it's accompanied by an extra trillion in tax hikes. That's like saying a $500 haircut can be converted from "irresponsible'' to "responsible'' as long as you withdraw the $500 from your bank account. If the super committee loses sight of this fundamental truth, it is doomed to fail."
