Jamie Whyte, in the London Times, explains to liberals that, no, there really is no such thing as a free lunch.

Children are selfish. Not because they are unkind (though many are) but because they believe in cost-free transfers. They do not understand that providing the toys and other amusements they demand imposes a cost on their parents. Children live in a fantastical world where Barbie dolls and trips to the zoo can be delivered without depriving their parents of something they might have enjoyed, such as a bottle of wine or a few extra hours off work.

Learning that cost-free transfers are impossible is an important part of growing up, and parents usually make sure it happens quickly. Most of us learn that there is no such thing as a free lunch long before we have ever picked up a bill.

Except when it comes to public policy. Encouraged by politicians, many adults indulge the infantile fantasy that the Government can bestow gifts on us while imposing costs on no one.
