OP is a project manager. This is different than a product manager (which I think you're referring to) or a program manager. I don't think there are many $100K+ jobs for general project managers. My actual advice would be to switch to one of those other roles

I hire project managers and I would say this is very location dependent and also very industry dependent. Find the right type of projects in the right industry and $100,000 should be very very achievable in a medium-cost-of-living city. It should be a no-brainer in NYC or SF.
That said, again depending on industry and type of projects, there’s a lot of risk in switching jobs for 20% more salary. How long until those projects dry up and you’re first out the door?
