Yeah, I get it, and you're not wrong - you'll probably end up with a higher salary operating that way. It's just not for me. I've already reached my "good enough" salary (the hard way), and at this point I'm more focused on what I can give back.
Statistically, with this setup, companies will constantly underpay. Yes, there will be some outliers being overpaid or those happy with their salary, but most will be in fact underpaid.
