What if tax brackets worked this way why can't the rich pay 70% on the first few 000 dollars too flat rate p?

It is not about if they have the money or they can afford to pay more, its about right and wrong, and making a person that has made a success of their lives pay for those that have not is wrong. What's wrong with EVERYONE paying a small flat rate. I'd like ot be able to go on line and search income of the US and give figures of how a flat rate would be a benefit over this progressive tax we have now, you know simple math, x-number of people making x-number of dollars equals x- number of dollars income tax verses what we have today, but amazingly you google that and it is not findable (though I suspect somewhere in the million plus hits that information is available but it ain't in the first 1000, do you wonder why?)
