The job market is a market, and if the job market dictates that the wage is set in part by one's ability to sell themselves to potential employers, then the (job) market is currently setting objective value (wages).

I'm not making a value judgement of your premise. Just pointing out that your argument works as well against you as it does for you.

From a pedantic economist perspective, yes. From a common sense perspective, if a £40 jacket was sold for £200 to someone, then it's still worth £40 even if this person overpaid for it.

Are people with bad information objectively correct? (Everyone overpays illogically for product because of deliberate misinformation, or whatever)
