Here is an example of a different type of error, from the part on Minimum Wages:
The first thing that happens, for example, when a law is passed that no one shall be paid less than $106 for a forty-hour week is that no one who is not worth $106 a week to an employer will be employed at all.
There is plenty of empirical evidence against this from countries that actually have introduced minimum wage laws. Even worse, not having minimum wage laws perverts economic incentives. Here's an example.
In Germany, people earning below a certain amount receive a basic subsidy from the state. It is a pitiful amount, but it allows them to pay the rent and survive. The problem is that this causes low-end employers to consciously pay their workers a ridiculously low amount, fully aware of the fact that their employees will receive additional income from the state.
In effect, the government subsidizes employers that practice wage dumping. That is clearly inefficient.
Now people react to this in two different ways. One camp says that the government subsidy should be abolished. But the latter is short-sighted, because society always pays somehow when people do not earn enough to make a living. Ideally, they pay via social safety nets, but if such nets do not exist, society pays in the form of increased black market employment and crime.
The other camp (me included) argues that this abuse of the system should be prevented via a minimum wage law. That would cut into the employers profits, but there's nothing wrong with that. It also wouldn't eliminate jobs, because we're talking about low-end sectors where demand is highly inelastic anyway, such as cleaning services. Hotels will still pay for the cleaning service, even if it costs them twice as much.
