I never said flat tax rate. 
SHOW US where I said flat tax rate. Good luck with that.  

In fact, if you look at my past postings, Im opposed to a flat tax rate. 
I and a friend of mine, did a study on this back in the 90s. 
It was obvious that a flat tax rate of 10% like they want to have, would not cover our budget.

I have said, and will continue to say, that it needs to be a PROGRESSIVE tax. 
However, I have also said that it should be 1% starting on somebody with a livable wage (say 25k) and above. 
Note that it should be 1% on the money ABOVE 25K. 
And with a top rate of 20-25% for those that get say $250-500+K.

In addition, this should be at best revenue neutral, or better yet, give us a balanced budget.

However, all of the money needs to be taxed the same. 
The idea that we have different tax rates is a joke.
