“To avoid having endless political strife and reaching no decisions, the President was given a lot of power.”

But the US system is famous for being unable to implement even the most obvious of decisions — such as having free healthcare for everyone. It’s practically designed to have almost continual stalemate (on domestic issues, at least).

And whilst it is true that some ‘Prime Ministers’ have little power, that’s often (such as in France and Russia) because they’re not really the head of government. In the UK, the Prime Minister usually wields enormous power — much more power (over domestic issues) than the President has in the US.
