I think they need to make jets at tough as C152's to withstand the punishment of pilots still learning how to fly when they transition on to heavier aircraft straight out of flight school. During Flt school most guys are taught by low timers these days still learning a hell of alot themselves
As opposed to the old days, when most people's first twin job was also their first airline job in the RHS of a DC3?
But then you're probably right... the DC3 was probably even tougher than a 152
