Because that’s where all the money is. Seriously look at global GDP, maybe American citizens aren’t the wealthiest but the country and the businesses that run it sure as shit is.
Haha pay is higher in the US because, sure, it's the world's largest economy. Though there are more millionares being minted in China than in the US every year. Nevertheless I'd sure as shit not want to build my business in China. I used to think this was because of relatively higher taxes in the EU than in the US but at the top end the highest wage earners are taxed rather heavily. A 500k salary is not 500k takehome…
Can I ask where in Germany?
