We posted a job for a certain compensation, they applied to and accepted the job at that compensation. If they could make more money elsewhere I don't know if it's their fault for accepting our offer, but it was their choice.
I don't think they were signalling their inferiority. Some we paid above market to, some we paid below market to. People we paid below market to we try to increase their salary to match market.
We never sold any intangibles, and the only intangible we offer but don't advertise is we're very flexible with hours and it's low pressure environment.
At the end of the day these are not children but adults who need to do what's best for them. If our offer and job isn't what's best for them then they shouldn't have applied and accepted the offer.
