You should, I maybe work 25 hours a week and and the only people in the company that make more than me are directors and C levels. And everyone on my team makes the same. Work life balance is important and working 20 or 80 hours won’t get you more pay, only more responsibility. I have one workaholic team member and we literally force him to take days off.
Your taking the pessimistic view, your salary is now floored by the highest quality most value producing person the company actually wants. If that floor is low then they clearly don’t want any rockstars on the team so kick your feet up and relax. And if the floor is high you found your group of live to workers.
I would rather work 50 hours per week and make a lot more now than have an "easy" WLB. Right now I need money, but the rules setup make it super tough (this plus progressive taxation that doesn't care how much money you average across life, just this year-- eg you could earn $1M in one year and nothing for 19 and still pay very high taxes while others earn $50k over 20 and they get an attractive rate).
