Honestly, it's the fundamental problem with capitalism, and while I personally advocate for a better system, it's not the sort of thing that can be put into place without major disruptions on all levels of society. Not to mention severe opposition from our allies at even the mention of such reform.

That said, the solution in the short term is to try to force people away from placing most of their money in nonperforming assets. Frankly speaking, getting the latest and greatest cars, smartphones, shoes, whatever isn't actually that much of a deal. The issue is the waste that comes from doing that so often. If all of these things actually lasted us a good decade (or 3+ for cars), it wouldn't be such a problem. Hell, we'd probably enjoy their use that much more if they were built to such a quality.

Imagine a smartphone that has a steel frame, engraved with a nice bezel pattern, and a colourfully etched backplate, strong enough that you don't need a protective case, and all its parts can be replaced by hand, or at least easily at any local repair shop? Sure, you might pay a few thousand for it, but if it's so beautiful, silky smooth to use, and easily lasts a good decade or longer, what's wrong with that? Especially if you can pass it down to one of your kids because it's still good and usable 15 years later.

I know there's software issues with such degrees of long term usage, but the thought that things might last more than a year or two has all but disappeared from most people's minds. It's sad that we're happy buying shoes that'll only last us 6 months of wear, just because you can buy it for less than the price of a week's Starbucks? I'd rather spend over $100 and get nice shoes that not only lasts me a few years, but feel good to wear and don't make my feet hurt after standing and walking around for 10+ hours a day.

On the other side, there's the issue that we don't have good ways to dispose of things. Human sorting is terrible and expensive, yet there's surprisingly little research into automating such processes because there's a lack of money to be found doing so. It takes government will to get these sorts of things done, but need awareness before the governments even start looking at such things in the first place.
