There's a lot more in that link than that chart thats not so pro Obama. Read more...
According to the link provided:
The 2001 & 2003 tax cuts don't just apply to the wealthy.
The 28, 33 & 35% tax brackets will increase to 31, 36, and 40%
Also the standard deduction for married couples will expire unless renewed.
The AMT will increase & # of taxpayors subjected to the AMT will increase.
McCain is against the above changes...which is good.
Obama's plan, according to your link, is certainly skewed to the poor and low middle class.
Obama wants the estate tax at 45%! McCain 15%.
Senator McCain would reduce corporate taxes and make research & experimentation credit perminant. These guys specifically say lowering tax and capital gains on business would be smart, as some of our competing countries have done. That is in opposition to Obama. They state McCains tax cuts must be offset by spending cuts.
One good thing is they both list 'eliminate oil & gas loopholes' (no details provided). Also provide credits for research & development.
There is a revenue raiser from Obama that increases taxes significantly but they list (unverifiable campaign provided revenue estimate). Not sure what that is.
They say Obama's 'Make work pay' program has incentives to make people work less and has a very high cost. They suggest the $ is better spent reducing taxes or the deficit.
They say Obama's plan to exempt people 65 & over from paying taxes if they make less than $50K is poorly designed. Seniors making $51,000 would pay a hefty tax.
"Many provisions in Obama's plan share a common shortcoming in their use of phaseouts, which reduce tax benefits over a range of incomes. These phaseouts adversely affect economic activity & growth. Furthermore add complexity to the tax code.
Obama vastly overstates the revenues he gets from offsets (they both do but Obama claims double)
Obama will provide tax credits for childcare to low income workers (good to try to get them to work but bad cause they shouldn't be having kids with no $ and we pay for their childcare)
Certain phaseouts will increase the affected tax rates on middle income earners in Obama's plan!
Obama will force companies to have 401K plans, which could be hell for smaller companies.
