To put a modern twist on the old axiom, a man who is not a socialist at 20 has no heart; a man who is still a socialist at 40 either has no head, or pays no taxes. Social Democrats are working to create a society where the majority are net recipients of the "sharing economy." They are fighting a culture war of attrition with economic tools. Defenders of capitalism risk getting caught flat-footed with increasingly antiquated arguments that free enterprise is a Main Street pocketbook issue. Progressives are working relentlessly to see that it is not.

Advocates of free enterprise must learn from the growing grass-roots protests, and make the moral case for freedom and entrepreneurship. They have to declare that it is a moral issue to confiscate more income from the minority simply because the government can. It's also a moral issue to lower the rewards for entrepreneurial success, and to spend what we don't have without regard for our children's future.

Enterprise defenders also have to define "fairness" as protecting merit and freedom. This is more intuitively appealing to Americans than anything involving forced redistribution. Take public attitudes toward the estate tax, which only a few (who leave estates in the millions of dollars) will ever pay, but which two-thirds of Americans believe is "not fair at all," according to a 2009 Harris poll. Millions of ordinary citizens believe it is unfair for the government to be predatory -- even if the prey are wealthy.
