Tax System More Progressive, Rigged

Maybe it's just a function of the rich getting richer and the poor getting poorer (but getting more handouts), but, according to taxfoundation.org, the federal tax system has been getting more progressive over the past 3 decades. In fact...

...today, the system is progressive (and rigged well) even after credits and deductions. A few things about this next chart: The jump between the $100,000-250,000 and $250,000-1,000,000 brackets is disproportionally large (stick it to the successful small businessman or senior-level corporate employee!), and the jump between the $250,000-1,000,000 and $1,000,000+ brackets is disproportionally small (the wealthy can afford top-dollar accounting and legal services). Also, the fall between the $15,000-30,000 and $1-15,000 brackets is below trendline, reflecting the impacts of the EITC and the welfare state. Clearly, the tax system has evolved to become more progressive and to benefit the wealthy (only an increase in effective tax rate of 1% between $999,999 and $999,999,999), and the poor, who pay progressive negative effective tax rates.
