It was not always the case tho. The work ethics of days goneby dictated you start somewhere, worked hard, learned and progressed in your chosen field. Easy credit was part of the problem. Young people took on big car notes, bought all kinds of 'toys' on payment plans and a lifestyle that matched their parents and older relatives, and not that of their parents when parents were the younguns' age.
It became almost shameful for a young person to be in a blue collar job or to work 2 jobs. They wanted it all NOW!
Work, be patient and it will come?
"Ain't nobody got time for that shyt!"
Currently, a combination of a dislike for manual labor and a desire to get to the top of financial security as quickly as possible, or to be more accurate, to have the trappings and appearance of financial success. Too many young people want too much too soon with as little effort as possible and while there is nothing terribly wrong with that (we all 'want' it) reality dictates everyone has to start somewhere.
