If your happy with going back to this that is your perogative but I would Be against your world view.
Salaries have not being keeping up with productivity gains as the economy has become anti-competitive by design. Every time money changes hands, it gets taxed maybe 30% on average... By the time $100 has changed hands 10 times, there is only $3 left out of it for the people (the rest went to the government). It centralizes everything around the government; money cannot flow too far from it. The modern economy is a giant social scheme with 0 merit. For many, it's hell on earth.
Damn it can someone please just give me free money so I don't have to participate in this system and don't have to think about it every day? Maybe if I could also benefit from it without having to work, it would be easier to just let it be. It's exhausting to get screwed every day and knowing exactly how I'm being screwed and yet having no power to do anything about it except whining online to random people hoping desperately that the system will improve just enough that I can get the tiniest opportunity. I've been working on side hustles for 10 years straight but I've never had the social connections to get traction regardless of how good the product is or how much users love it.
If I befriend Elon Musk and he makes one tweet about any of my existing projects, I'll be a millionaire within a year. 100% guaranteed. I wouldn't have to change anything or know anything more. Then I would have impostor syndrome instead.
It's easy to claim that anyone who receives help and has it easy 'suffers' from impostor syndrome and anyone who doesn't receive any help suffers from Dunning-Kruger effect. I know how this works. Only those who really struggled can see all sides; that's because nobody tries to hide anything from you; there is no incentive to.
If intelligent people cannot separate the monetary system from capitalism, the average person won't either.
But sure, keep wishing we could go back to feudalism or whatever, great plan!
As for car loans and home loans... Similar thing. If people couldn't get loans for houses, real estate prices would have to come down to an affordable level that people could save for. If people couldn't get a loan for a car which they need as part of their small business, they could sell equity in their business to raise money for the car.
The question above are circular. How would people get loans if loans didn't exist? They wouldn't, we don't need them and society would be better off.
