Who do you blame for the US Financial Situation
Thirty years ago, cable TV, microwaves and air conditioning units were luxury items that had high manufacturing/maintenance costs for their time. The maturation of the technology has brought down those prices. The masses can afford these items now not because of better economic well-being, but because the service providers/manufacturers have been driven by competition to lower those prices.
A 4BR house and an SUV would have cost the same (sans inflation) 30 years ago, and most probably the same 30 years from now (if SUVs aren't banned/replaced by then).
