It boils down to a simple fact: we don't like doing things we don't have to, and constantly look for ways to get what we want for less. It's a very primal thing, and I don't think you can ever fully legislate your way around it.
Hear, hear!
Rational agents always seek to maximize their satisfaction.

No economic verity is more fundamental than this one.
And people with piss-poor ideas of how to do that will maximize their satisfaction for short-term gains instead of long term gains.
Example: A huge percentage of middle class American school children, since at least the 1960s, have decided to maximize their short-term satisfaction by consciously choosing NOT to do their schoolwork to their best ability. They have consciously chosen not to learn basic arithmetic, basic grammar, basic writing skills, basic reading skills, history, science, literature, etc.
The fact that this is a really effective way at locking them into piss-poor jobs with little opportunity to advancement is a long term problem they don't care about until later. And while they shirk the work of preparing them for the future (paid for with copious amounts of taxes gleaned from hard working folk), they simultaneously practice being lazy and irresponsible.
And then they will blame it on "the system" instead of their own choices.
Don't get me wrong. Capitalism has serious structural issues that need to be mitigated to an acceptable level via legislation. I completely get that. But every other large scale system has serious structural issues that need to be mitigated via legislation in some manner.
One of the really important things to keep in mind in this discussion is that capitalism moves the bar of what is acceptable towards "more and better stuff". The working poor a few hundred years ago had no concept that they were entitled to a home of their own. They rented rooms in in cheap establishments and shared the rest. Boarding house or flop house come to mind. The kind of 2 bedroom apartment that activists now deem essential for civilized living is way better than what many in the middle class aspired to when my mother was born. Indoor toilets? Woo hoo! Running water? Woo hoo! Air conditioning? Woo hoo! A car for each adult? Woo hoo!
Do we need better labor protections for workers? Hell yes.
Do we need affordable health care for everyone? Hell yes.
Do we need to reduce the ability of the ultra-rich and corporations to influence legislators with money? Hell yes.
Do we need to structure our tariffs so that countries that have piss-poor environmental protections or piss-poor labor protections or piss-poor civil rights suffer a big penalty to get their goods in our country for sale? Hell yes. And conversely, if they do better than we do on those topics then our industries need to pay a big tariff to sell competing items. That way, instead of countries rushing to the bottom to attract industry, they'll rush to improve the ecosystem, worker protections and civil rights.
But capitalism, with its structural issues properly mitigated, is the goose that lays golden eggs. It would be foolish to kill it.
