In an advanced industrial democracy like the United States, who should bear primary responsibility for ensuring an adequate social-safety net and a reasonable level of economic equality?

Strangely enough, Sen. Bernie Sanders (I-Vt.), the once and possibly future presidential candidate, thinks that’s a job for corporate America. Who would have thought the first step on the road to democratic socialism would be to privatize it?

Or so one concludes from reviewing Sanders’s proposal to tax large employers (500 or more employees) $1 for every dollar their workers and their family members get in means-tested federal benefits such as food stamps or Medicaid.

He says the plan would prevent giant corporations run by plutocrats such as Amazon’s Jeffrey P. Bezos (owner of The Post) from passing the tab for their underpaid employees’ well-being to the government. “Corporate welfare,” Sanders calls it.
