Those who think they should pay more may always do so, there is nothing to stop them from writing checks to the gubmnt.
If they think Nanny G does an exemplary job of distributing their spare cash, go for it I say! Just dont, bill gates, speak for other mega billionaires on the planet. You, bill, get to speak for YOU and only YOU.
personally,
i like it when the 1% and the 5% and even the 10% get to exercise largesse by supporting charitable institutions they value close to home. Us local folks working the events appreciate it when the local tycoons show up at park fundraisers, library galas, and etc. —makes us feel valued.
one-size-fits-all federal gubmnt solutions, delivered impersonally by bureaucrats who may or ir may not be competent, is not the way to my heart.
