That's not an honest question. From Bernie's point of view it is what does our tax rate need to be to meet the standard of providing for the general welfare for our citizens.
Why isn't it an honest question, please explain why? The narrative coming from socialist pundits like Sanders continually use the 1% to proclaim that there is no need for someone to have that much income, then throwing out data on how many people live paycheck to paycheck? (See Youtube Video)
Between those two ends are a lot of context that is left out.
It is fair to ask how the rich became rich, yes.
It is fair to ask how someone living paycheck to paycheck is in that situation, yes.
As the questions above are explored, we would realize that for the "rich", many worked hard and earned the rewards of their efforts. Some we would learn they took advantage of "the system"; tax laws, loop holes, low wages, all the while reaping only for themselves the rewards. And there are those that are in the middle of even those examples.
For the those living P2P, we would learn of those that have made poor personal choices related to education, financial, and careers. These personal choices led to their current situation. Capitalism isn't to blame, the life choices is the blame.
We would also learn of those, by no fault of themselves, where the hand they were dealt is no fault of their own. Job loss, market decisions, divorce, a failed business attempt, Covid-19, etc. I believe in social safety nets to help those that deserve the help.
So as I read your response there is a limit to one's personal wealth. Beyond that you would take, through taxation, and give to others for their general welfare. So how much is too much? And define maybe paint, at a high level, what the "general welfare" for citizens look like through the means of taxation?
