The HQ is a blatant cash grab. It is going to cost $10 billion all said and done, IMO, once the bidding war is over. This is a trillion dollar company and $10 Billion is a rounding error. But the taxpayers are going to get soaked for a minimal gain.
Foxconn get $4 billion and it looks like the plant will create 13K jobs, most of those NOT the high paying jobs mentioned. And all the payroll taxes of these employees will go to Foxconn, not the government. $4 bill for 13K people? How much for 50K workers?
The EU bans these types of competitive bidding wars, and I wish we had a functional government in the US that did the same.
