The younger generation have always tried to project an image of wealth, often based on overstretching credit.
During the so-called "Yuppie" boom of the 1980's i worked with and knew many contemporary professionals who were up to their neck in debt, but still called their generation "the wealth creators".
6 bedroom house + BMW + lots of clothes and holidays, leveraged off multiple loans and credit / store cards.
Well, it is called deficit spending and governments have been doing it for years.
My parent's generation had few if any credit cards and they were paid off in full when due. They normally saved up to pay cash for things and the only long-term debt they had was a mortgage which eventually was paid off too. They drove used cars and let someone else absorb the high initial depreciation on new cars. Vacations were short weekend trips by car and not the 2 vacations a year to the Caribbean. In the end they were net savers and could pass on their wealth to us baby boomers. This type of fiscal prudence was likely the result of surviving the great depression and a world war.
All that is quite a contrast to what later generations have devolved to.
Both my current wife and I inherited most our parent's financial ways and that has stood us in good stead over the years. Our modest home has been mortgage free for many years, I retired at 56 with a good company pension plan and benefits and we have savings. The end result is that we are comfortable in our retirement. To me that was what being middle class got you.
As far as current generations go, I think they can go screw themselves if they haven't figured out the mess that they have gotten themselves into.
