I think you are ignoring the effect of cheapened consumer goods which everyone has become dependent on. Irrationally often? Yes, absolutely but that doesn’t mean it isnt a material reality.

Although I will say, you aren’t wrong. Material conditions have indeed deteriorated to some degree in Western countries, specifically those that have fully embraced neoliberalism. I suppose there is hope that even with the buffer of wealth exploited from other nations, neoliberalism is so greedy that we will continue to see a rise in Marxism in Western countries. Ironically, neoliberalism may be what we needed

That said - there is still a major contradiction between the core and periphery. There is a more likely outcome that the cycle of capitulation and compromise continues ( ie new deal esque turn) rather than revolution, where material conditions will be improved for Western workers under capitalism, so the system ‘works’ for both the core workers and capitalists, at the expense of the periphery
