I'm still mulling this over. We are talking about income tax where you are talking about accumulated wealth.
I applaud your attempt at fairness but on the other hand your suggestion would reward the wasteful and penalise the frugal saver.
I've already said the rich needs taxed at a higher rate, but I'm talking about income not their wealth.
The problem with eating the rich is it is only one meal and not a permanent solution.
No, I'm not suggesting we reward the wasteful and penalize the saver. I've speficially said I wouldn't want to tax equity directly. Without taxing equity directly, it's impossible to have people pay an amount exactly equal to their share of wealth. But it's a number meant to show how imbalanced it currently is.
Those that bring in the most income, often have an even larger percentage of wealth. That's because the wealthiest people are not generally deriving income from an external source; they're generating income from their own capital. Their own businesses, their own stock, bonds, and partnerships, etc. Income from those sources is typically taxed at a low rate. And those that do not have capital, are in a difficult position to ever increase their wealth.
It's because it's not progressive enough. The American tax system isn't very progressive. A lot of fiscal conservatives talk about increasing the number of people that pay taxes, but most people have a very tiny proportion of the overall wealth. In many cases, even income taxation is regressive, with the highest earners paying less than those in the middle class.
It seems to be a matter of picking the number that is most favorable to the wealthy. If I make $70k, and my neighbor makes $35k, and I have $100k in equity, and my neighbor has $10k in equity, should I be paying 2x as much in taxes, or 7x as much in taxes, compared to her? In this case, I should argue that we should base taxes on income, while she should argue that we should base taxes on wealth.
What I'd propose is that we tax income and consumption, but in a way that I end up paying a significantly larger percentage than her (because her income is so low, it doesn't leave much room for capital appreciation, whereas I have a significant amount of disposable income that I can do whatever I want with, such as squandering it on excess consumption or using it for capital appreciation). And If I make $20 million and have $200 million in equity, then the same thing applies.
That's the principle behind progressive taxation. Those towards the bottom of the income spectrum have basically all of their income eaten up by necessary consumption. As income grows, one has more and more opportunity for wealth accumulation. So taxing at an increasingly higher percentage, the wealthier one is, up to a point, keeps the system stable and fair, while still allowing people to have the fruits of their labor and fortune.
Otherwise we end up in our current situation where we have the highest income inequality in the developed world, lackluster primary education systems, not so great infant mortality rates, difficult to afford colleges, and various other problems.
