The Romney proposal is of course a charade. The top brackets already have most of their deductions phased out by AMT. So Romney's plan to cut rates and get rid of deductions, means that the rich simply get lower rates. Deductions are not a factor in the taxes of the top bracket (except the charitable deduction and does he really plan to get rid of that?)
In contrast, the rate reduction for the lower brackets won't be very helpful since rates are already low. It's the mortgage interest deduction and the standard deduction (and a lot of other smaller ones) that reduce the amount of taxes for working people significant.
So it's a fake proposal, of course. Ridiculously, nobody in the debates (including Obama) has called him on this phoney plan.
I think the answer to your question is contained in the question. Obama will not "call him out on it" because Obama knows that to do so would expose the fact he has no facts to base his campaign allegations on.
So you hear Obama say it on the campaign trail and yet wonder why he doesn't confront Romney with it? - Surely you see the answer to that dilemma. Right?? You are bewildered?? I think not.
Oh- and would you kindly point out ANY point of Obama's plan and explain how (as you bemoan the lack of GOP explanations) just how it would help anything.
I note that you said we need to raise the tax on the 'rich' - you need to define that. Do you really mean the uber-rich? Because it that is what you mean, then it has been demonstrated over and over again that there are just not enough of them to make any difference at all. You could CONFISCATE their entire fortunes and you would be able to run the government for less than half a year. THEN, whose money would you confiscate to make it through the rest of the year? That dog won't hunt.
OHHH = you mean to raise the taxes on those going down to 250K - that would indeed bring in a lot of money, but that doesn't sound so good on the campaign trail does it? THAT is the region where all the small businesses reside and it is the small businesses in this country that provide for its prosperity. If you increase taxes on THEM, you kill the job growth.
And it is the millions of wage earners that provide for the bulk of the revenue for this country. We need JOBS - millions of them - to turn this economic train wreck around. Taxing the very source of these jobs will necessarily result in fewer jobs. A vicious cycle that we see taking place in front of our very eyes month after month.
The recent drop in 'unemployment' is NOT the result of robust job creation - it is the result of so many people just giving up looking for a job. There have not been enough new jobs to keep up with the growth in population.
Obama is an abject failure - in every measure by which presidents are gauged.
Obama is the charade - actually 'empty suit' is the preferred pejorative. He came to the presidency to BE president - not to ACT as a president. He is nothing but a community organizer (race-baiter and rabble-rouser) who has fewer credentials that anyone in my memory.
Worship him if you want - but you should be careful not to embarrass yourself in the process.
