Giving everyone the ability to exercise their creativity, pursue their passions, take care of their families, while simultaneously eliminating poverty would make the US less competitive globally? I just don't see how.
You're only looking at the idealistic pros and none of the cons. Competition is about who's working the hardest. Imagine two companies, Company A in which workers are extremely hard working and Company B which workers are free to pursue their passions and only work when they want to. Which one do you think wins out in the long run? And I'm not talking about a version of Company A in which everyone is unhappy, worked to death, etc. I'm just saying more work = more productivity, which is what competition is about
