I see how the charts indicate a strong trend of the devaluation of employed persons in America. It only proves my point: The wealthy have persisted in devaluing the average worker, and overvaluing themselves.
Apparently, you are viewing the data through the lens of your own bitterness.
I see the share of income for the top 1% (and to a lesser extent, the top 20% -- but you'll have to look at the raw data to see it) increasing over time, but it's wildly variable. The dates where the increase peaked or fell back correspond with the boom and bust periods in the US economy. That's because the top brackets income get a large proportion of their income from capital gains.
To realize a capital gain, one has to invest (and risk losing) capital. That capital funds new business ventures and expansion of existing businesses, It's what grows a company faster, and creates jobs. If the capital sits on the sidelines, the economy stagnates or even declines.
Nobody wants to pay taxes; you're right. But that doesn't make my point mute. Maybe you're bitter because you couldn't buy both a boat and a benz last month.
I think you mean "moot".
But, since you seem to think I'm one of the wealthy, I'll have to disappoint you. My car is 6 years old, and I'll probably drive it another 4 years until I can save the cash to buy a new one. I paid off the mortgage on a modest house last year, so I don't have any long-term debt. The only significant investments I have are in an IRA and 401(k), because I've been contributing as much as I can for the past 20 years. With a bit of luck, it will be enough to retire on, without depending on Social Security.
However, the period 1979-2007 almost exactly mirrors my path from the bottom 20% to the top 20%. And that's what detailed studies have found: the population of the various quintiles are not static. People generally move upward, with new people filling in at the bottom (as they enter the workforce as young adults or immigrate to the US). Furthermore, the average income for all quintiles has been increasing over the past 30 years, albeit at different rates.
You've got a choice: either start valuing people fairly yourself, or get ready for the government to do it for you.
You've got a choice, too. Either get off your butt and work to improve your own financial position, or wait for the government to bail you out. Which strategy do you think is more likely to succeed?
