If the guys hoped a job every 6 month for the past 4 years then they've been hired _every_ _single_ _time_ they hopped. People hire job hoppers. If they didn't then they'd (by definition) stop job hopping. Sure maybe after the 10th hop it'll catch up to you but by that point (in this scenario) you've had the equivilant of 10 14.8% raises which IIUC is a total ~404.6% raise. So you're now "stuck" at a job making 4x what you did 5 years ago.
