At worst - same with a much smaller deficit (better).
We already know that Bush's combination of 2 wars + big tax break brought this country on the brink of a 2nd depression.
On the other hand, Clinton inherited a small recession from H.W Bush, increased taxes and the country's economy grew like gangbusters and we actually had a surplus.
Now, the 70% top tax rate is idiotic imho, because history has shown us that it did not work with the modern global economy (see the 70s), but we have also seen that the 33 % top tax rate failed with the last year or Reagan, H.W Bush as well as W. Bush. The magic number seems to be around 39% to 50%.
We are currently at 37% but corporations tax has been cut dramatically which is, to be fair, the same as giving a top-end tax rate (it is not the middle class and the poor that own these corporations).
So - like everything in the world, some kind of in-between thing should probably be right. We have seen that the 39%-50% range brings growth to the modern American economy - early years under Reagan, Clinton and Obama.
I honestly believe that this is likely the magic range.
