Do working people actually buy all that high priced stuff they use on these shows?
Only way I can see many people doing it is on credit. Personally, I prefer to build as I can afford, hence my stuff will never be "magazine quality" or done quickly.
Debt comes from the implusiveness of people's desire of not wanting to be seen as "not having" status symbols - a big house, fancy cars, nice clothes, the latest doodads - because they allow themselves to be made to feel inferior for "not having".
It is all one big farce.
