Government intervention in the economy always has the opposite of the intended effect.

This is because government is a gun. It says Do it our way or else! So whatever action individuals are forced by government to take, it will be against market forces. This means someone is going to lose. Someone is going to have to act against their judgement and suffer the consequences.

Plus, government edicts must be enforced, which requires manpower, which is expensive. So money will be taken from the market and paid out to government employees to do work that the market does not call for. That is, useless work.

Often, people find that working around government edicts is slightly less expensive than following those edicts. Either way, it calls for expensive and unnecessary work, which reduces the overall supply of goods in one area or another.
