We live on a planet of 7 billion+ people. The first world disproportionately consumes a ton of resources relative to the third world. Our consumption is not sustainable. Workers in the first world do not want to give up their luxuries so that workers in the third world can be uplifted. Hence why the working class voted for Donald Trump. They want to build the wall to keep poor third world immigrants out. They don't want to share resources with them.
A lot of first worlders struggle to pay for the basic necessities because our "floor" for basic necessities is far higher than the third world. We don't have scrap metal shacks like in Bangladesh. We are seeing an increasing trend of first worlders living more like third worlders. Poor tenants sharing a one bedroom apartment among 4 room mates. Putting up wall dividers. This is a fire hazard. A health code violation. But it's either that or out on the street for you. We are seeing more Tiny Houses. And municipalities are shutting those down because of "violations". The first world needs to live more like the third world just to be able to survive nowadays but the first world won't even allow you to do even that due to regulations. We are seeing people live in their cars. And the authorities are cracking down on that.
In the minds of the average Trump supporter, they fundamentally understand that you can not have a decent first world life and have mass immigration at the same time. This is why even /r9k/ sees socialism as a pipe dream.
There is no global worker solidarity. Workers just wanna get theirs. First world workers do not want to sacrifice whatever comforts they have left in order to accommodate third world workers.
Even within the first world, there is no solidarity. No one gives a fuck about anyone but themselves and maybe their inner social circle. And even then people only care about what their inner social circle can do for them. The only person who will ever care for you is your mom because she's biologically driven to love you (even that is a maybe depending if you have a shit mom or not) and maybe your dad. People just care about their own situation. They don't trust anyone. Not their fellow comrades. Not the anarchists. And certainly not the politicians or the police.
Everyone is a docile cuck who is afraid of losing their jobs. People are uncomfortable but too comfortable to actually fight. And the people who have nothing to lose (ie. lumpens) feel hopeless. They know that they can't enact real change. The number of totally destitute people in society is too small for them to really do anything collectively as a group. The wage cucks who still have something to lose are too docile to join the fight and risk whatever comforts they have left. So the destitute go buy fentanyl-laced heroin on the street or deepweb and waste away. Or they start selling drugs themselves. Or selling their own bodies. Turn to organized crime. Turn to "carding" and cyber-crime. Whatever it takes to survive.
