One way to set this up is using some form of consulting/temporary worker company as an intermediate. I was employed in that form for a while. So legally that company hires you and then invoices the U.S. corporation taking a cut. In my case that was Kelly Services and was hassle free (I got my salary as negotiated in time, only interaction I had with them was signing a contract and terminating it) no idea how hard this is to setup or what the cut is they take.
Someone else will make huge money only because bogus laws in Germany which probably won't be fixed even in the year 2100.
Anyway, I really like the idea and it sounds totally hassle-free. I will contact them and ask. Should I give you as a referral? Maybe you get a check if it works out for me.
About bogus laws: I think the employee protection in the German system is a factor (not the single one) on why German economy did quite well and populists for a long time had limited success. The strong safety gives guarantees so that one has less fears and representation of employees on the board ensures long term perspective over short term gains. (With the downside that employees on the board represent current, not future employees and leads to more conservative operation as change is hard) Anyways, that's a different complex debate.
I don't know if that company is best. Just gave it as reference, also for finding competitors. I think for most part you'd need a company with a representation in U.S. and here, so that your "practical" employer can do a contract under U.S. terms and you do one under German terms ... and not sure they'd remember me - it's 10 years ago :)
