If you drop your fees so low your customers get pissed, well then, you'll loose customers. Or if you can't afford to maintain infrastructure, then you'll lose customers due to your unreliability.
A race to the bottom is the reason we have 60" flat screen TVs that are better quality and cost a fraction of what a similar TV cost 10 years ago. It's a good thing.
The race to the bottom in the airline industry was entirely driven by consumers who were willing to put up with crappy seat just to save $10. They got exactly what they wanted.
That said, we are seeing a shift toward premium economy. Basically some airline said "I'll bet there are some customers will to pay more to get more" and they were right.
HN likes to talk about the "race to the bottom" as some failing of capitalism, when it's actually working exactly as it should. "The market" doesn't get it right every time - plenty of companies make the wrong trade off - but the consumer is the ultimate decision maker if the tradeoff is worth it.
And it often ends up warping the market so that choice is removed, a premium economy does not always spring up. To take your TV example, modern mainstream TVs now bundle spyware/malware/adware. Yes the hardware is better than it was, but it is being invisibly subsidised by the reduction in ethical standards. And now none of the major players can now afford not to do it if they want to compete. Is this exactly what people wanted? The market no longer offers allows them to choose and they aren't being fully informed about the implications.
It's really a failing of marketing - being unable to continue to justify the price of a product (whether it was warranted or not).
No one seriously argues against weights and measures legislation. We've supposedly had an information revolution but I still can't really trust any source of product information online.
Another good example is FDIC insurance. We could have little to no banking regulations, but that would also introduce a lot of uncertainty and result in wild swings when the economic situation changes. Tell depositers that the gov't will back their savings helps stabilize the banking system which actually benefits the market (the same way a stable and predictable government/legal system benefits the market).
When you wrote "as some failing of capitalism", I believe the economic concept of "market forces" would have conveyed the same message better, compared to the larger concept of capitalism, which is essentially a political ideology that can trigger disagreement from people who have benefited from competing political ideologies like socialism.
Essentially, what I'm getting at is that a race to the bottom can happen as long as there are market forces at play, even if the society itself is not running a pure capitalist system like China (which IMHO is a cross between capitalism + communism vs. capitalism + democracy).
For instance, Uber China was forced to quit in 2016. They sold to rival Didi Chuxing because they couldn't keep up with the race to the bottom by them.
In the case of airlines, customers thought they (only) wanted the lowest price, so airlines (helped by non-transparent UIs at ticket comparison sites like Expedia, Kayak, etc) actually reduced the quality of the product by removing features (pillows, blankets, food, drinks, seat size, seat selection, changeability, eligibility for upgrades, etc).
Premium Economy in most cases is just charging customers for what they used to get in Economy.
So now TV manufacturers are supposed to sell the razor at or near cost and make it up on the blades of user surveillance.
Would people pay another $50 or $100 to turn it off? It's not clear that they'll ever get the chance.
