One key difference is that Startups lack fund.
So either:
1. Funding be made more generous by offering tax advantages to invesitors
2. Or, biggest expense are employees, so we need employees accepting a dream stock unit and very low wage, so we can hire more of them.
But I've talked with German employees, literally, none of them will accept more money for more work. There is very strong emphasis on work life balance unlike US. So only way to overcome this issue is to get larger funding and that's smth government needs to fix.
That way startup can become more competitive.
