We have serious issues like housing shortages but if we kicked out all the immigrants (which we shouldn't because they are helping our economy by doing jobs we don't like!) we still would have that problem, just a few percent less. This is the fallacy in that narrative.
And life isn't all about who has the most money, that's a US-Centric view. The poorer countries in Europe are better places to live at the moment and cost of life is lower there too. Besides, those 'entitlements' really add to our quality of life. We don't have to worry about going bankrupt over a medical issue. That's much more important in my life than being able to buy a new iPhone every year and pollute the world.
It's very telling of the US to always consider everything some kind of race or competition. Whereas we're not trying to win but to live together. Really if I make enough money to live comfortably without having to waste all my life at the office I'm doing well. Life is a balance of work and personal life. The US has never had this kind of balance. Everyone's in a race to make it 'to the top' but most people never do. I hear of people in the American big cities having to take side jobs because cost of living is so high. Our American-centric HR is always pushing me to 'challenge my career path' and move up into management but I would utterly fail there due to just not having those skills and talents (Peter principle). I'm just happy being a top technical expert for the rest of my life. I would detest being a manager and I would suck at it.
If anything Europe is getting too American. Too few people are holding too much of the wealth, this is why people are protesting.
