You cannot tax your way to prosperity. You can not redistribute wealth to create prosperity.
The current highest tax bracket for singles and married couples is 35%. Do you really think the Federal Government deserves more than a third of people’s income? This despite our congressional politicians inability to even keep a balanced budget while throwing billions of tax payer dollars into bailing out companies and rewarding their CEO/COO/et al with exorbitant severance packages as reward for their “good” work. If you still think the Federal Government should be allowed to keep over a third of your income then only you should have to pay that amount in taxes while the rest get to keep their current lower tax rate.
What really should be asked by Americans is why Federal Income tax rates are distributed the way they are: 10%, 15%, 25%, 28%, 33%, and 35%. Why is there such a huge jump from 15% to 25%? Changing it to more logical 5% increments would still end in the top 35% currently in use while lowering taxes for three brackets that make up the bulk of the American working class. But then there are few Washington politicians who want to lower and distribute tax burden in a genuinely balanced and fair system while cutting out pork and other wasteful government spending.
“We want to take money and put it back in the pocket of middle-class people,” Biden said. Of those who would pay more, he said: “It’s time to be patriotic … time to jump in, time to be part of the deal, time to help get America out of the rut.” 
So Biden thinks he and his ilk (politicians) should get to decide how wealth is distributed in this nation regardless of how hard a person worked to earn that money. No thanks. I have no desire to see this nation start heading back to the days of ridiculously high taxation that existed prior to the mid-1980’s.
Biden need to remember this: people do not have the right to equal wealth in a capitalist system, but people should have the right to equal opportunity to earn wealth. That opportunity can not be achieved by taxing the wealthy. That is what (wanna-be) neo-socialists like Biden do not understand (or choose to ignore) in an attempt to ignite class warfare for political gain. Opportunity breeds wealth, not taxes.
“It’s time to be patriotic,” he says in the ad, “…time to jump in, time to be part of the deal, time to help get America out of the rut.” 
What a load of crock. Paying taxes has nothing to do with patriotism. Americans have been paying taxes for generations because it’s the law, regardless of whether they are patriotic or not, and because the majority of people accept taxes as a means of enabling communities to establish and maintain infrastructure, education, and so on.
Wealth redistribution and taxation to pay for new programs and existing failed programs will result in further degradation of the U.S. economy as those with the money and business will cut jobs or simply leave from being overly burdened. This taxation will also discourage innovation as anyone making a profit off their inventions will be punished for having the temerity to make “too much” money for their creativity and ingenuity. It’s highly likely should this policy put in place we could even see a brain drain out of the U.S. as more entrepreneurial friendly nations lure America’s best and brightest away from oppressive taxation practices.
I suspect these neo-socialists, along with their counterpart corporate neo-cons, fear the rise of a wealthy class that would could come about from a society of genuine equal economic opportunity. They have a vested interested in keeping the poor and working class exactly where they are: divided and squabbling over scraps.
