I quit my job, they wouldn’t pay me median wage for my career after I made them $750k in 3 years. I was paid $150k (less than 50 a year)

I made friends w Hr and looked at my billable hours and rate, they charged clients $750k for 3 years of my work and gave me less than $150k so they were effectively making $200k a year in profit from my efforts. I left and found a job and now make double.
