As someone who also feels they’re evil (left 5+ years ago), I will grant that it’s not all bad like many here like to think. I imagine many small businesses and nonprofits derive a lot of value from their community building and targeted advertising, which is (maybe) a good thing.
That being said, it’s a good idea to understand why the pay is so high (and it’s not because they’re nice people who only want the best for their employees):
You will be expected to leave moral qualms at the door. This an unwritten rule at many companies, but Facebook had to write it. That says something.
You will be expected to work for it. Hard. The people I know at Facebook easily put in 1.5-2x the hours I do at a FAANG-ish (late nights and weekends seem to be the norm), but get paid roughly 1.5-2x what I do. If that’s a tradeoff you’re willing to make, go for it. I however am making more money than I know what to do with, and thus value all the time I’m not working (hobbies, travel, side projects, etc) way more than the money I’d make from working during that time.
At the end of the day you aren’t going to singlehandedly destroy the fabric of society all that much in your first year, so you’re fine making the above sacrifices for a year or two for some quick cash then fucking off to pursue some real interests, go for it. But I sincerely warn you against sacrificing too much of your life (youth especially) and morals for money —- it really isn’t as valuable as it’s cracked up to be.
