But for the purpose of answering your original question, during the period between 1982 and 1989, in the aftermath of the Reagan tax cuts, income inequality was growing but there was a pretty steady decline in the poverty rate (and by implication, an increase in the size of the middle class).
Being above the poverty line does not equate to being middle class. Your deductions are haphazard, nonsensical, and filtered through the spooge Grover Norquist left in your eye.
