This is a common but unfortunately very narrow perspective. Frequent lateral moves can inch you upwards but asymptotically to a limit.

If project manager's in OP's area make $90K, no amount of job hopping is going to making him a $350K earner. Agree all else equal, better earn $95K than 90K but the better bet is to break out of that range.

Just lateral moves won't get you there. You need a different strategy.

At least in my experience, you need the job hop to get the change shift of role, industry, or promotion as well. I would be doing my previous bosses' job and then some, and show it in review cycles, only to get the 'yeah you're right, just wait a bit longer, we'll figure it out' over and over again. Leaving for another company was the only way it happened.
