I already pay thousands of dollars with current rates -there is no ing way I would ever vote for a candidate with this tax plan that would make me pay thousands of dollars more, though I can easily understand why young people would be attracted to it, since they don't yet have full-time jobs that would require them to pay such high rates, so it isn't real to them.
What if you got healthcare that was overall substantially cheaper due to medicare's bargaining power in exchange for your higher taxes, causing your take-home pay to rise slightly?
For some folk, they make enough money and pay enough taxes that single-payer is a bad deal, but overall for most middle class and working class people single-payer saves them money. IDK what you are, if you live in NOVA and are a Yuppie (no disrespect, you seem like the competent smart professional type) you may be one of the small group of people hurt by an uncapped medicare payroll tax.
