Book piracy is a big reason I've been able to learn as much as I know about ML. I don't know how to feel about it. All I know is that I'm more effective than I would've been if I had to pay for the books, since I wouldn't have read anything. It's common on HN to pretend that everyone here is an affluent programmer working for FAANG with $500k/yr in stock vesting. In reality, I've spoken to many who are more along the…
An alternative to "Never buy a book" that I think is more fair is buying a couple of copies after I'm finished with a book and sending them to others if I find I enjoy them.

If you mean "go work for someone," then certainly. But that involves working for someone. Almost everybody on HN works for someone; many are less well-off than they seem. Students, for example.
One reason this is true is that GCE offers $300 credit for new accounts, and TFRC emphasizes that you should sign up for a new account before activating TFRC. $300 ain't much. If that didn't matter, they certainly wouldn't bother mentioning it. Yet $50 is 1/6th of $300.
Of course, buy them if you can afford to. I probably didn't emphasize that enough.
