3. Even per capita we are 21st in the world, not bad especially when you consider that as that number gets bigger the return you get on it diminishes.
I honestly don't know if this is happening in the same way with American companies, but to be honest, if it's not that would make me want to take a hard look at the reasons for it. Lack of effort from the government to make those deals, or inability to make attractive deals - which would be a rather worrying indicator of the american industry's health.
By completely exiting, Trump is effectively leaving the field of renewable energies to other countries. By relying more on burning fossil fuels for energy he can definitely give America a short term boost by preventing energy costs from rising further, but he might also cripple its renewable energy industry - which employs more US citizens than Oil, Coal and Gas combined.
Trump wouldn't have had to exit the agreement to do what he wants by the way - the agreement does not have any penalties for not fulfilling it, and it allows every country to adjust its own goals in the agreement, without asking anyone else for permission.
What countries are you talking about? What mythical poor countries have tools and expertise and what not? And to compete with us against what?
We've moved to a global economy and basically doing what wealth of nation stated, we have specialize in things we do best while other countries specialize on their own thing. If Swiss and Japan wants to make awesome watch go for it. If labor is cheaper in China then okay. But they can't and have not taken higher end skill set. You just can't export those.
And you just side step the world being screw to concentrate on our country. But at the same time OP addresses that with saving our coastal property.
The mega cities that make a boat load of GDP is Los Angeles and NY which will be screwed with the rising sea water.
3. The US gave $31b in foreign aid. Which sounds generous, until you do it per capita. In which case the US slips way off. The closest economic comparison would probably be the EU which gave $87b away. I, like many, consider charitable giving and aid a sign of strength, not a reason to whine about how unfair life is when you're the richest.
