You cannot cheat an honest man. Honest men do not need to study praxeology. Many honest men lacking formal education can spot an untrustworthy promise a mile away. Nevertheless, many people persistently follow economic mirages. Parents want others to pay for their children's education, so, they trust the government's promise to teach their children as they wish, despite the government's clear economic right to control what it funds.
Free enterprise teaches using sound economic laws.
By seeming to repeal those laws, the welfare state seems to obviate learning them. Here is a classic case. In California, Proposition 103's promoters promised that enacting their measure would cut twenty per cent from the voters' automobile insurance bills. The insurance companies' attorneys replied that it was un-Constitutional, and said that legal appeals would make drivers living outside urban areas subsidize those living in them. After the people voted in Proposition 103, the Californian Supreme Court stripped out all but the rate-levelling provisions.
