I think it is cyclical. Most of the guys in yeshiva kollel that are in the mid 20′ and upwards were mostly raised in homes where parents worked (as was the custom) in the 1970’s through recently. Lots of them grew up with modern comforts and therefore when the time came to get married wanted it continued (nice car, support gifts etc..) This group will not be able to give the same to the chidlren that they are raising. Those kids will end up going to work to break out of the lifestyle of living on the basics. Their kids will go back to yeshiva. This is not blanket rule but rather the “norm” Lots of kids growing up want to be different from the way they grew up.
its a never ending cycle……….
enjoy the ride
