I feel it may collapse in the next 10-15 years because everything has become so top heavy. We were told for 40 years that everything would trickle down to the plebs, but what we've seen instead is a reduction in the price of goods and cost of credit, and a massive hike in utilities and house prices.
Meanwhile, billionaires and shareholders have benefited from the sales of national assets, and cuts to public services which have funded tax cuts for them and the highest earners.
Low-wage globalism has given us the cheap goods, but increased margins for huge multinationals. It's unsustainable, as you eventually run out of developing-world labour. Shifting this shit all around the world isn't exactly carbon neutral either. It's a system that damages lives and the planet.
The rich, may yet, get eaten.
