You are exaggerating as you say yourself, but these things are mostly not issues at all. You just hire people (and that does not cost much: made a company including employees a few weeks ago for 1000E first year including accounting and payroll, no work from me; if 1000E is an issue, maybe do something else) to handle them, and, you put some provisions in for the stuff you mention, like in the US, to use your ranting language, you do for the over the top insane crazy bonkers legal crap you have there and find normal. At least paying some poor sod I have to fire a few months more does not keep me up at night as I know this upfront. Legal shit does but that's not relevant in the EU (sue me, see where that goes). You are used to the one, I am to the other.

The real EU problem is on the one hand conservative nature: almost no way to get significant investment here without actually proving you already (before you started!) can pay it back 10x. And then what you rightly say: this is not a union (yet): most countries just don't mesh and the language and culture barriers are somewhat crippling. Not how you say because those barriers do not exist anymore for decades already. Not like the current US yet but things take time: think you had some civil war and such. We are still recovering from border altering world wars and some idiots cutting up this continent like it was a cake after. Let's give half to an idiot Russian dictator and let's not bother to remove Franco. This takes time. Unless you install an actual dictator for the entire thing, this takes time in any place.

Not sure if these will be solved ever but not in my lifetime.

And another cultural thing: I like free time: that you do not probably means something you might want to discuss with someone, but working all hours of the day is something I do not miss and do not wish on anyone.

And as last point: what company do you run or what is your yearly turnover? Because, besides all your ranting, there is the real meat. How is the great US of A working out for your personally with all its blessings? Because I am afraid it will be slightly disappointing after all this. I mean with my 8 weeks a month vacation I have time to write tripe like this, but you...
