Make laws that give consumers mandatory, irrevocable warranties that include fit-for-purpose clauses, and has phrasing such as "reasonable expected lifetime" for the goods. Make those laws apply to whoever sells you the goods, not the manufacturer.

Laws like that weed out a lot of crap. Shops won't buy crap in because they have to deal with the warranty on said crap. Manufacturers won't make (as much) crap because they have to deal with returns.

You won't be able to buy a $4 air fryer any more, but the one you do buy will last a lot longer.

Edit: I'm Australian, and we have consumer rights over and above warranties offered by manufacturers. Those rights would be a good start.

They start about half way down this page:
