Simply holding a ruler up to the graph you cited reveals your conclusion to be complete bullshit. If the straight-line trend that obtained up the early 1970s had continued then the indexed compensation would be closer to 130 than the 110 it currently is. What sort of idiots do you take us for?

Don't even get me started on all the rent-seeking and tax acrobatics surrounding non-wage compensation. I would much rather just get paid cash and pay a somewhat higher rate of income tax than waste time trying to optimize some endless menu of benefit packages that require the skills of a CPA to analyze properly.
