Policy-ineffectiveness proposition

The policy-ineffectiveness proposition is an economic theory that suggests that when the government tries to help an economy, it may not be effective. Basically, the idea is that government policies can't always make the economy better, and sometimes they could even make it worse. It's important to note that this is only a theory and not a fact, so it's important to carefully look at the data when trying to understand how the economy might respond to different kinds of policies.
