A better way to address this problem would be to treat welfare benefits like taxable income. Even low-income workers with no income tax liability have to pay Social Security and Medicare taxes. But welfare benefits are entirely tax-free.

As Reihan Salam has noted, Sweden has a generous welfare state. But Sweden treats welfare benefits as taxable income. This gives even welfare beneficiaries an incentive to support efficient government, providing a welcome blur between “makers” and “takers.” In Sweden, according to Tino Sanandaji, “an astonishing 85 percent of working-age native Swedes work and pay taxes, far above the European average of 70 percent.”

You could even increase the scale of welfare benefits, in order to ensure that the taxable net income to welfare beneficiaries remained similar. Such a change would allow for more straightforward comparisons of income from work and income from welfare, and reduce the disincentive for work.

Obamacare is doing much to make it harder for Americans to find work, especially full-time work. At the same time, the aging of the Baby Boomers and the growth in welfare payments is making it easier for Americans to give up on looking for work. Absent reform, this won’t end well.
