Fohat, you have to understand, the US is severely under-spending in its industrial base.
Our GDP is almost entirely fictitious, with little to no investment in production/mining/refinery activity.
Our population is also an unkempt mess, they are not only unruly, but stupid. They will not be slaves, fine, but they also refuse to be engineers.
So here we are. What's next for america. Realistically, chances are if we do not enslave South America we're done for. It is horrible, but IF our definition of growth is in the context of EMPIRES, that's our only option.
The other path is, enter the chrysalis, and become the butterfly, EAT 100% VEGGIES. FAT CHANCE that'll happen.
