A lot of middle class Americans could take this path if they did without and the kids worked as soon as able for extra money for the family (you know like you have to when you have no other choice) but we have to have the nice home, white picket fence, big SUV, expensive sports, iPads and android phones, and as soon as the kids turn 16 they must have a car of their own, etc...
Modern life by design now (it is designed) requires more and more to get by. You need a car to get to work because of the awful thing called suburbia. You need a expensive cell to make sure you get the call for that job offer. Where you had to submit a PDF copy of your resume which you had to type on a computer somewhere and have access to Internet to send it.
The downside is you miss out on this fabled childhood luxury that has only been a thing for the last 80 years of human existence.
