> In the usa we have an overemphasis on the president, but we’ve slow walked ourselves into a dysfunctional congress that just can’t do anything.

Isn't that cause and effect? In essence, what the US is showing is that the executive has so much power now that congress is largely obsolete.

If there was a better balance of power and less executive power, the only way the executive branch can get something done is to work with congress.

Obviously that doesn't work in all cases, conflict in particular. But in my experience that's where most democracies have drawn the line on executive power, basically for emergencies.
