QE wasn't a mistake, QE saved our shit lol. Europe is recovering slowly but surely thanks to market based reforms. Just look at spain. Greece is the exception but they are beyond fucked
About our current system...
I want to say that it'll be stable since our economic arsenal is getting better with time. By that, I mean that the level of rigor employed is insane; the Fed probably couldn't have stopped a crisis of 2008 magnitude 20 years ago. Even now I foresee central banks moving into a NGDPT regime soon that further smooths out the business cycle and ensures financial stability.
As for big banks, stronger international standards, fewer information asymmetries make me optimistic.
Yet a small part of me is still scared as fuck that we're nearing another collapse. You're right to worry about Chinese debt, for one, and I think that contagion from that is something we need to prepare for.
I personally am really concerned that regulations will be rolled back a bit too far. Niggas wanting to ditch Dodd-Frank entirely is madness, I work with people like that, they are not nearly as calm and informed as they should be yet they are the voice lobbying against regulation.
Honestly though, we should be fine. Hopefully. Maybe. Probably, though.
Not my job, but I'm assuming it just depends on local regulation and your credit??
Lots of asians in finance, don't be discouraged by your race.
Idk what I would do as a CS grad. The world is your oyster. Find out what appeals most to you. If you like finance there are many ways to break in as a CS major. But if you prefer something like security or frontend or whatever, stick to that.
I do like my job, my bank offers protected Saturdays so I can safely plan things without having to be called in. I've also always loved economics so it's nice something related for a living. It's not a white boys club dude, if anything Asians are over represented. Most of my friends are Asian.
