The biggest real-life plot holes and you didn’t expect something that directly affects 8 out of ten people (and indirectly affects the other 2) on the planet to come up?
Anything that affects that many people is going to have real life plot-holes:
America nominally fought its last war in 1945, but we’ve had soldiers fighting and dying in dozens of countries ever since.
Fossil fuels and unregulated pollution is proven to be destroying the recent period of relative climate stability and fossil fuel companies are getting paid by the government to stay in business.
America produces enough food to feed the entire country(and probably several others) but created laws that force you to throw it away.
