¿Por qué se mete el estado en estas cosas?

Esta gente no entiende que un intercambio voluntario no tiene lugar si las partes no consideran que les conviene:

Do you employ unpaid student interns—college students who work in exchange for on-the-job training?

If so, President Obama's Labor Department says that you're an exploiter. The government says an internship is OK only if it meets six criteria, among them that the employer must get "no immediate advantage" from the intern's activities. In fact, the employer's work "may be impeded."
