The USA has one of the most insane systems on the planet. There's 50 states plus DC. Each with their own laws which apply to anybody selling in that state, so if a business is selling in 50 states then they need to follow 50 sets of laws, and that's before we get to smaller jurisdictions. The tax system is byzantine and nightmarish even by the standards of tax systems. What the USA has going for it is that it was very far away from its enemies during WW2, and so while European countries had to rebuild everything, the US economy went into overdrive. Plus it's the 3rd most populous country in the world and that has advantages. It's certainly nothing to do with simplicity of doing business.
