I know your $5,000 vs. $50,000 figures are very rough, but $5,000 in 1960 would be $36,855 in 2010 dollars (and after taxes is not trivial, e.g. the personal exemptions that sheltered average families from the full and very high tax rates in the '50s were largely nullified by inflation over the next couple of decades before Reagan started a variety of corrections).
What additional insight do your numbers provide?
One thing I added was "doing the math"; yummyfajitas didn't go that far (which is no reflection on his posting) ... plus I think it's useful to point out just how significant inflation has been over the years.
To me, this makes the comparison exceedingly easy to understand.
