It's completely possible to go high quality and low price - it's precisely how China is pretty much taking over every single industry in existence. But in the US you tend to pay low prices for junk, or unreasonably high prices for ostensibly high quality. I think that's largely because of implicit collusion between companies in most industries, particularly those with high barriers to entry.

So for instance see the Phoebus Cartel. [1] It was a cartel in the US (and Europe) including General Electric, Philips, and others that engaged in a wide-ranging conspiracy to exploit the market for lightbulbs. They intentionally lowered the quality of bulbs, driving planned obsolescence and thus increased sales, and even engaged in spot [un]quality checking of cartel members to ensure that nobody's lightbulbs would last too long.

In modern times I don't think companies would usually be so overt, but there's nothing illegal about unspoken cartels doing the exact same thing. For instance even in the video game domain, up until the PS4 era major players used to subsidize game console hardware to a wide degree. Then with the PS4 Sony stopped stopped doing that, and simultaneously so did Microsoft. In a competitive market that's exactly when you'd go subsidization to the extreme, to clinch the market to yourself. But so long as both companies agree to stop subsidizing hardware, then they both stand to make a whole lot more money. And that's exactly what happened. In the end, the consumer ends up with worse hardware, pay more for it than they would in a competitive market, and companies make way more money. I think that makes it fair to blame corporate greed.
