When they complained that a fee was charged for attending his lecture at the university and that, hitherto, lectures by visiting scholars had been free-of-charge, Friedman replied that previous lectures had not been free-of-charge in a meaningful sense: lectures always have related costs.
Kada su se žalili da je naplaćena naknada za sudjelovanje na njegovim predavanjima na Sveučilištu te da su, dotad, predavanja gostujućih znanstvenika bila besplatna, Friedman je odgovorio da prethodna predavanja nije bila besplatna u razumnom smislu: predavanja oduvijek imaju svoje povezane troškove.
