Why mercantilism has been argued to be a poor approach to use in order to promote economic development and prosperity?

Mercantilism is often criticized for prioritizing national wealth accumulation over individual prosperity, leading to trade imbalances and inefficiencies. Its focus on government intervention and strict regulation stifles competition and innovation, which are essential for economic growth. Additionally, mercantilist policies can result in colonial exploitation and restricted market access, ultimately hindering broader economic development. This narrow approach can create short-term gains for a nation while neglecting the long-term welfare of its citizens and global trade relationships.
