There are plenty of people in the world who flee economically capitalist Countries for ones that are MORE socialist, in fact much of far right Europeans are using xenophobia to attempt to secure power based on that very fact. Its folly to argue "no one is going to socialist Countries" while vaguely gesturing at political refugees considering that there only like 7 Countries remotely considered communist or socialist and none of them claim to actually have achieved either.
And diminishing the people who suffer under capitalism is a comically misguided position to take. It stinks of the perch of convenience of living in an imperialist Country for whom the only detriment of its imperialist behavior is now possibly having to pay market price for products, fuel, or having to live next to people from the Countries destroyed by capitalist pursuits. Its hilarious that you would mention refugees earlier without mentioning how their Countries got destroyed. The destabilization that caused my Father's Family to flee a SECOND entire Country, was done on behalf of the United Fruit Company, so Americans could have cheaper bananas, sugar cane, and coffee. Within 2 decades that Country was known for radical polarized death squads, and it has never recovered.
But hey I'm sure you'd have a lot to say to them about how the flavor of racism and poverty thei experienced here was like...designer racism and poverty, because at least their own people weren't trying to kill them!
Lastly, I dont recall arguing for a specific system. See unlike you I dont need to draw lines in the sand to feel comfortable about where I live, or my political perspectives. I am skeptical of capitalism because it's been at the root of almost every major World conflict once you get past all the religious nuttery and arent blinded by racist/xenophobic grievances. I'm not fully closed to the idea of market economics, and if you had paid a little attention to discussions I've had with other leftists (who tend not to have better solutions themselves other than an idealized barter system, or who are okay with authoritarian socialism...which I'm NOT), you'd have known that already.
What I do know is it's a measured fact that the more diverse US Society has gotten, the more the majority demographic has consistently voted down social programs. Voted for someone who dismantled free college, and are currently against forgiving student debt despite that it would do WONDERS for the economy and bolster struggling markets (people cannot spend what they do not have), voted against Medicare/Medicaid expansion to single childless adults (the most in need would be minorities), drummed up the political imagery of the "welfare queen (I'm not gonna even ask what race you think that welfare queen is), want to defund public schools, are in favor of privatized prisons who farm out labor, and they're perfectly willing to do this WHILE paying 2-4x the prices for goods while corporations post record profits, push for further cutting of their taxes, rolling back of child labor laws, are capturing local resources (water) and markets (real estate)...and people who think like you are perfectly willing to vote out the kinds of people willing to fight them over this because you hate the idea of more Spanish-speaking brown people coming here.
Sounds amazing Bro.
