3.5 Billion people in the world make less than $7/day. People may live outside the US, but they don’t have the same consumer appetite.

They have the appetite. They mostly don't live in economies that enables them to earn money.

The US was a unique money-making machine... Although the gears seem to be getting looser and the machine is being broken. Personally I think the US economy is flexible enough to mitigate much of the damage, however I worry about the future impact of political changes.

I'm in New Zealand which is quite wealthy although the demographic timebomb will go off in next decades: and our economy is also fucked because our voters hate businesses and business people.

One strong signal of how fucked a country is economically, is how well small businesses can survive.

If the US starts screwing its businesses more, that is the time to worry.
