Could you open this a bit more because I’m not sure I understand your perspective currently?

Reading Marxist theory helps. Here's a pretty good lecture of comparing the systems which gives a pretty good overview:

The History of Capitalism, Slavery, Feudalism and Marxism Richard Wolff

a weird perspective to things that at least I don’t know of

Thank you for acknowledging that you might have a perspective missing (This is by design). Considering this, you could benefit exploring terms like "hegemony" and "ideology".

what else should they do?

To me it seems that you think you're asking a rethorical questions with no answer. If you engage with Marxist theory, play with the thought, you don't have to adopt it. Doing so you might realize that there are answers to this.

If, and only if, the mother could get a higher paying job in a different location which would raise the entire family’s life quality, they absolutely should move even if it would feel difficult at first. Some (capitalistic) countries even offer support for that (if they were unemployed at first).

Again, you're advocating for people relocating and adapting to the market. Meaning, people serving the economy and not the other way around. This doesn't fix the systemic problem.

Of course it does. I’ve done it, multiple times, and I can’t understand why someone would rather be stuck in a shitty situation instead of moving into a new location where they have opportunities to build a better life.

How is someone who lives paycheck to paycheck to just move? Who rents to someone like that? Moving costs money. What if someone doesn't have the social support for moving? You're saying this form a very priviledged position. It's not a free choice. It's being forced on you, because bourgois politics doesn't tackle the problem at it's roots.

Sure, cherry pick some numbers here

You're saying it like you don't do it.

China has made numbers out of thin air for a long time and it starts to show now that their real estate industry is in shambles

With a liberal perspective it sure looks like that. This is not cherry picking, right? lol Most of your treats come from China..

Cuba vs. US, well, given the list, cherry picking is cherry picking.

Well considering one is the hegemon, the other being an embargoed island with restricted access to the global economy it's impressive I would say. Show me another country with this many sanctions and that high of a life expectancy.. Libs ignoring context, a classic duo...
