It is a bit of leap to go from 'I am doing well but some things aren't working' to 'trash it all and let's do the late 19th to early 20th century economic system again'.
We live in a world of abundance where kids in developed countries (UK, US) still go hungry, and it got worse in the past 10 years.
I don't think most left-ish people like me are asking to a return of 19th/early-20th century economic models, we are asking for a return of social democratic values over the hegemony of markets and finance. It's not that hard to imbue some humanity back unto an amoral system, we know now through empiric experience that pricing simply has not taken into account human suffering and externalities wreaking havoc into our environments, we just look for more humane ways for markets to function. Left to their own devices markets will only seek profits, at all costs, we, the people and workers, are the ones who can steer it into boundaries where profit-seeking isn't, ultimately, life-destroying.

I agree there are plenty of net positive regulations made by good systems _at the time_. But it’s not producing good regulations _now_ and is very resistant to change.
