If you are able to get a job at a FAANG, you should also be able to take a look at your expenditures and determine what you actually need in life. Maybe getting a smaller living place will be the stumbling block for most, but think of the freedom you gain. If you find yourself fantasizing about working in Costco during your daily life, chances are the things you spend on aren't that effective at bringing you satisfaction anyway. Yet unlike the vast majority of people you actually have the means to escape and build the life you want i.e. a massively well remunerated job with remote working options. So why not do it?

I once took a "down shift" job and it didn't work well.

After only a few days I started seeing inefficiencies, some people slacking like crazy while others had to work for two, management that was really incompetent and could not be convinced to improve anything.

I mean, people were nice and everything and I enjoyed the social aspects of the job, but I learned that I was too competitive to function in a less demanding job

Inefficient for the company maybe, but if you are not going to be paid more for extra work or diligence, and the work you are doing is not particularly meaningful or helpful to others (could be wrong as I don't know what we're talking about) why would you work hard unless you are larping?
