America is the best nation in the world at quite a few things! For instance, they have a proud, expensive military to likes to fight wars for decades regardless of if it causes a trillion or so to be added to the national debt. They are the best at dividing people across racial lines.
They are spectacular at imprisoning their own people over petty crimes, like Marijuana possession. They are great at convincing people that make around $25 an hour that people that work in the service industry for low wages are the real problem, while their boss makes $800 an hour lounging by the pool.
America is wonderful! You can buy political influence to give yourself a tax cut every year, while failing to maintain roads and infrastructure. The income inequality gap is #1!
America is great when it comes to Healthcare! Your treatment depends on an insurance company whose sole motive is to profit.
America is THE BEST place in the world, if you are a millionaire. Otherwise, I'd keep looking.
