Is it OK then for China to keep the Yuan artificially low to tank the US economy?
As for your comment, just an explanation as to how we became a debtor nation.

Well, you know what they say, there is no honor among capitalists and thieves

I don't think the Chinese are keeping the Yuan artificially low in order to tank the US or any other economy that is a major buyer of Chinese products. Maintaining a relatively low Yuan keeps Chinese exports attractively priced which keeps Chinese factories busy and its economy growing.

We became a debtor nation under the greatest generation every. We baby boomers are just following in their footsteps although doing it bigger and better.

Who's footsteps? I'm pretty sure the boomer generation pretty much owns the level of greed and narcissism of it's generation all into itself. In fact it produced none other than Donald Trump.
