"What makes you think the problems of immigration are not just Trumped up (heh) " - what do you mean?
Certainly most people who own houses in the suburbs have been aware for many years that some of the problems with illegal immigration are making for an uneven playing field for small business and average workers. I'm not sure if city living folks are as exposed to the business dealings in the same way.
In what ways "very hierarchy and filthy-rich class... of people that has steadily been fucking over the lower- and middle class,"
In what ways do you mean? My only guess is you mean the wealthy have convinced both democrats and republicans for years to avoid minimum wage increases that match living wages?
"filthy-rich class (that your president represents)" - If you mean he represents the rich because he used similar methods to get rich in the past, okay - like a token symbol? IF you mean he represents them in his current government role, I think you are wrong. I think many of his policies are very contradictory to what the wealthy wanted. From replacing O-care to the illegal immigration enforcement, these issues are things most of the wealthy have been against from what I understand.
Scapegoating as a tactic for either side is annoying.
When you say "evidence that immigration is terrible", please understand some in the US are rallying for complete open borders, most are saying legal immigration is not terrible, it's good for the country, and we want the process to be better. A small few are against immigration, however it appears that certain media outlets and those who want to change the course of democrat vs republican want people to think that enforcing the laws that have been on the books for years means people are evil, racist, and want no one to enter the country.
Both sides are saying different things about the same thing. It appears the republicans / conservatives are listening the to media and social justice warriors, hearing what they are saying.
Stronger elements of socialism? Europe style? What do you mean? Work or don't work, we've tried more and less feed stamps, rent vouchers, healthcare things for the whole country and state by state these things have varied and swung a bit one way and then the other. So yes there is a lot in between.
I don't think most of those things are going to make much difference with the rich vs poor actually. I do envy some of the programs I have read about in the UK and other countries that are close, but the populations here are very different, and country wide things are major.
One of the things that actually is working to put pressure on wealthy to put more money in the pockets of the lower and middle class is limiting the amount of readily available people who will work and live illegally.
You say "your president" and then later say "we should go for" - so I am confused as to whether you are outside the US or in it.
There are many pieces to these complex issues, what works in Detroit is not going to work in Burbank. Scapegoating a person or class you don't like is not helping to put facts on the table, just appealing to emotions and encouraging others to buy into the group feels.
