were you the one that proposed the flat tax? Can't remember.
They should pay more, because they earn more., and the impact to them is nothing compared to what it is to the lower earners. Clearly you put brackets in place, but in no world should someone making $70k a year be paying the same medical premiums that someone making $200k a year does. Health care has become insanely expensive, and reduced the take home funds of the middle class, becoming yet another direct shot to the ability of the middle class family to sustain.
Those who are in the top 1-2% of earners should absolutely be paying more across all facets of taxes, healthcare premiums, etc.
