>that's why its economy is so much more dynamic than European economies
What do you mean with more dynamic?
What do you mean with more dynamic?
It doesn't have any meaning other than to invoke this common US belief. It's part of the American exceptionalism story.
Those things are how dynamic the economy is. It's hard to measure in a rigourous way, but in the US it is distinctly easier for a business to start/expand than it is in the EU.
Digression, so I can get shot at from all sides: This dropped under Obama. Again, it's hard to put concrete numbers on it, but things started happening more slowly - I suspect because regulation became more onerous.
