I don't think either of those are a problem. The problem is that we need more healthcare, more jobs, better jobs, healthier food for the poor, better education, etc. If we have to tax the hardworking doctors, or take more or even most of the billionaire's money, then I'm quite sanguine about that. So be it. I think using taxes as a weapon against people is wrong though. So - to say that because some billionaire pays a lower tax rate, because his income comes through capital gains, that we must punish him with steeper taxes, or a wealth tax, or whatever plan you suggest, then I believe that is not only unproductive but also immoral to do so. The basic problem is that the government is a poor steward of our money. Take education as an example. The US spends more money per student when it comes to education, and doesn't have outstanding scores in math, reading, science, or any category that I'm familiar with. There are problems with our education system, it's unequally distributed, it's not preparing kids for the careers of the future adequately, and other problems - but what's the solution? Spend more money, tax more, and so on? On a similar subject, why should we take more money from the rich, who already pay a disproportionate share of federal taxes, so that we can buy more tanks we don't need, invade foreign countries, overthrow foreign governments, staff military bases around the world, and waste uncountable amounts of money on silly military projects.
