Leftist economics have severely reduced the number of real jobs, or given them to non-Americans. Burger flipping is now the only job left that is open to out of work people. After replacing those jobs with robots, there will be very few people earning a salary. Where will be customers come from?
Will the only people working be lawyers and politicians? Who will pay their salaries? other lawyers and politicians?
The “world” knows it could never beat the USA in war. The only way to beat the USA is economically. Once the USA has been reduced to a third world economy the military will be but a paper tiger. The process is almost completed. Trump is spoiling everything.
