Oh wow, I had the exact opposite reaction. Very close to a childhoold in poverty - lost my family when I was 5, adopted, homeless, etc. - but when I graduated college, my apartment rent was $2000 in DC, I was vacationing in Norway, and eating and drinking at the most expensive restaurants. I made a bet that I was going to make decent amount of money in salary, and that bet has paid off. Debt-free from university, sizeable retirement accounts and savings, etc. Now, I wasn't able to afford to buy a home or condo at 25 like my peers, but I thought I was okay given I was starting over.

I realized I lived through a peculiar hell when I was young, so I definitely made up for it buy working hard, playin' hard.

As an immigrant who grew up with nothing and have no family support network, now that I make ridiculous money working at FAANG, I spend it all because I know I’ll be fine if I go back to nothing.

That seems irresponsible to me. Shouldn't you be at least saving enough to never have to go back to living like that, no matter what happens, knowing how it feels? Knowing how to live like that and actually living with nothing are 2 different things.

> I spend it all because I know I’ll be fine if I go back to nothing.

It's good that you'll be fine if you go back to nothing, but it very much isn't a reason to spend all the money.

Reasons to spend all the money could be eg that it makes you happier (I very much doubt that) or that it makes the world a better place (you didn't say how you spend the money, so perhaps?).
