The US economy has been fluctuating since our colonial days under British rule. The US economy can be seen to rapidly expand every 54 years, more or less. Lewis and Clark expedition, Louisiana Purchase, Panama Canal, landing on the Moon were five of these expansive episodes. It does not matter who is president, nor which party is in power. You can see the graphs for yourself if you google it. The problem is after a huge expansion, it is always followed by a contraction. Hang on everybody because I think there is another contraction just about due.
