The US are a shithole that stays afloat because the population is kept tame via populist discourse and seeded in-fighting.
And after reading your comment, I find myself wondering how so many people, from my country included, go to the UK to work. Sounds a bit like US but a notch down.
We all make our choices but you could have chosen other countries, with better social networks.
I have been making contributions towards my national pension fund since I started working and enjoy a free access NHS. When I eventually reach the age of retirement, which now is around 67 years of age, I’ll be granted a pension based on my contributive career.
I’ll still be able to keep working if I choose to but most people don’t and others are barred from it, like judges, surgeons, police officers and even politians, as they are seen unfit to hold crucial positions.
And this applies to all emigrants that move here, with some added conditions, obviously, but still are eligible for these social benefits.
And regardless all of this, you can and should save (products with special tax exemptions exist for that exact purpose) if you expect to maintain a specific standard of living.
