The US dollar is just paper, like toilet paper. They can print $100 bills for 4 cents at the Treasury or mint or wherever they “make” money. It’s all phoney, just like the statistics given out by the government, professional wrestling, sit-coms and much of the news we see on TV.
Buy gold or silver and store it for a rainy day as insurance. Make sure it’s in a place where the government won’t look for it.
