But now you're making a subjective statement about the pay. Without context (supply, demand, how much revenue you generate for your employer), how to determine what is highly paid?

I fully reject the idea that more hours should be a requirement for good pay.

Further, as a startup founder myself, I don't want my employees working much more than a 40 hour week. I have found* I prefer the work produced by someone with work-life balance, than someone who works all the time.
