I can understand that. According to the numbers we were a hell of a lot better off in many ways 40 years ago.
Median income 1971 - $9,000
Median income 2011 - $45,000 to $50,000
(hard to find an exact number that hasn't been "adjusted" by the government)
So individual median income has increased by a factor of 5 while most consumer goods have increased by a factor of 10 or more.
And a huge part of that is because of big increases in the tax burden on individual items, on manufacturers and on businesses.
They pumped your gas, checked your oil and everything else under the hood, checked the tire pressures and you never got out of your car.
When I look at ratios of income there is no doubt higher taxes come into play. Home values went from 2.5 times income to 5 times. Total taxes paid today, no matter who you are, is about 55%, as the federal, State and local government spend 55% of GDP.
