I"m not sure I understand this “analysis”. There is only 20% of the population in each quintile of the income distribution. You can’t get more people into the top 20%, you can only throw more money and tax benefits at them.
Here’s a good graph of this phenomenon. Note that the top 20% and especially the top 5% went almost asymptotic in 1980 – I wonder what happened then? I’m very grateful that I picked up on this by about 1985 or so and shifted my focus to personal financial management rather than working uncompensated overtime in the hopes of promotion. {{ LOL }}
Reminds me of the college president that got roasted years ago when he said his goal was to get more students into the top half of the class. {{ LOL }}
