One big reason why the younger generation hop from on job to the other isn't because they are impatient, although some are but it's cause they want to get one that the pay can be good enough for them to be able to meet up the bills and all the rest. You mentioned that in the olden days, it was quite easy for them to purchase houses, pay for bills because the economy was bearable so since it's not the same now, you find them looking for jobs that can enable them work from home to at least cover for the area of transportation.
The only thing is that the younger generation should learn to be as hardworking as the older ones where because some of the youths we see now are so entitled and feel that everything should be handed them.
