You're right, and I should've addressed you more directly.

Job hopping is the result of competition in the labor market, and while some may find it unfulfilling, that is usually the exception, and macroeconomically speaking, more job hopping can be really good for the overall market. That's all I was saying, though I forgot to mention how competition in the labor market relates.

My definition of job hopping is to switch jobs continually until you find the right fit, the right fit including wages as a factor among many others. I suspect that your definition means jumping jobs arbitrarily for the highest wage. In that case you are right that job hopping is bad, and it's my fault for confusing job hopping as wage increasing mechanism vs job hopping in general.
