As a non-US citizen, many questions popped up in my mind, after reading your post. You mention...
aaa) The number of millionaires. One site said 24.5 million, another 23.7 million.
bbb) 36.8 million Americans living in poverty in 2023.
ccc) These days, it doesn't take much to hit a million dollars in assets in the US
ddd) And, the number of millionaires in the US is bound to grow
To me, it seems the numbers are not right. Why?
aaa) If the number of millionaires are bound to rise, what would happen to the number of people living in poverty?
bbb) If it doesn't take much to hit a million dollars in assets in the US, why don't the number of people living in poverty reduce? (of course, exceptionally, there might be a few who choose to be that).
Other than the above, there are many who complain about the extreme cost of health care etc. For example, right here at AN, I've read many posts from US citizens who have settle in Thailand just for that reason.
Looking at it from outside, for a non US citizen it is quite difficult to understand what really is the issue.
US is looked upon as the most powerful, developed country on the planet. It spends Trillions of $$$$$$$$ on war, space programs and the likes.
So why cannot it be made a paradise for its citizens to lead a peaceful, comfortable life in their home country, at a reasonable cost? Why not the people living in poverty be given an opportunity to raise their living standard? Why doesn't the Government prioritize this and why don't the US citizens demand this from their Government?
I am sure, the US has the capacity to do that - Financially, Intellectually, Technology and what not...
