"There Is No Such Thing as a Free Lunch"
Friedman’s favorite line was "there is no such thing as a free lunch." His meaning: behind every seemingly free benefit, someone is always paying the bill — every generous outlay of government ultimately comes from taxpayers or from inflation. With this plain saying he repeatedly warned people against naive illusions about government intervention. With this uncompromising faith in markets and formidable powers of expression, he became one of the most influential economists after Keynes.
