Theoretically a lot of that is true for the US.

It's just that

- both parties have undermined the separation of power, and expanded power of the president repeatedly for many years (e.g. with granting special privileges to the president after 9/11 which where way to broad and not strictly limited to a very short time)

- especially Trump has undermined/dismantled a lot of "checks and balances" mechanisms, including in his previous presidency

- people spreading "legal theories" which are very clearly nonsensical but at least half of the countries press pretending they are credible potentially true. As some are about the constitution you can see this as a direct propaganda attack against the US constitution. With close no consequence, too.

- the current supreme court is IMHO strange. They are not at all impartial and have interpreted laws multiple times in ways which are neither backed by the laws wording nor it's spirit (if you based the spirit on the history due to which the laws where made) with this decision often having been reasoned by what looks a lot like "make pretend everything is normal excuses". But at the same time it hasn't gone fully "we go with whatever Trump/Mega wants" or anything like that. I can't really understand what they are thinking, tbh.

so yes, the president has too much executive power at the moment. Both more then intended with the founding of the US, and in practice more then they even legally have.

Who forms the cabinet though? In a two party system - where one party seems to be built around a personality cult - cabinet can be filled with rubber stampers
