I can’t see how this is corrosive for society exactly, but this strategy exists because it works (even though it’s not without some downsides). Churning isn’t free, the employee/customer has to commit resources to churning, and especially in the case of an employee, accept risks. You’re always going to have some churn, so no matter what approach you’re taking you always have to tune the incentives so that churn occurs at the level you’ve deemed acceptable. If retention becomes dramatically cheaper than acquisition, then the existing customers/employees really only have themselves to blame.
