It's all about perspective. You're going to make plenty of money - I've been working for a while, I don't care what things below 1000$ cost - I have more left over than I spend regardless, and the mental bandwidth that's been freed up by not having to look at prices is very rewarding. It's scarcity vs abundance mentality. Another way to look at it is - when you're out there working, making say a phone app, and you find out it is costing them a million dollars, and it's a bug ridden piece of shit - you'll look back on this textbook, that was written by very smart people, proofread, etc, and it only costs 190$.
