US Law (local/state/federal)

I don't think you could skip to the end like that. I mean you can't sit here and take the current House of Representatives and remove it from the United States presidency. It's way too ingrained and affected to make a good judgment about its abilities independently. I mean honestly how much of the House Representatives right now do you think could be called direct vassals of Donald Trump? How much has the house representative been completely tarnished by how US presidents have behaved in the last century? How much of their power have they surrendered willingly and for political reasons to the presidency? In ways in which the founding fathers never envisioned?

As for presidencies being a trade-off, well the most recent government refusing to form a coalition was caused by a President in France. So clearly that doesn't help. Legislators refusing to form a government just means they should be replaced. Which is how it's supposed to work, which is much more responsive to the will of the people really. But it's not like those governments shut down entirely in the meantime. There's still an apparatus.
