I'm pretty sure he is saying the Republicans are wanting to lower taxes for the rich. Also the current tax % that the richest tax bracket is being taxed at is one of the lowest ever.
The highest tax bracket (as far as income) is one of the lowest in the modern era. Of course, that was offset in the 80s by the introduction of taxes on capital gains, sources of revenue for people that were not previously taxed. Sure, the highest tax rate is lower now than it was in say 1998 (by like 3% points), but the tax rate on the middle class has been dropped even more to the point of being eliminated for many middle and low income earners.
If you crank the numbers, we might could all realize that raising taxes won't fix our budget issues. In fact, if we dropped the bush tax cuts on the highest income earners, there would only be a roughly 75 billion USD increase in revenue (ignoring entirely whether GDP growth would then slow). If we dropped the bush tax cuts on middle and low income earners, there would be a roughly 200 billion USD increase in revenue (subject to same caveats). That won't hardly close the gap on the 1.4 trillion a year in debt that president Downgrade in racking up. This is all about class warfare and trying to get president Downgrade reelected.
Nobody wants to make deep and serious spending cuts and program changes to military, medicare, medicaid, and social security spending. Everyone is worried about getting reelected and catering to society that is, by and large, incapable of cranking the numbers themselves. But spending is the problem, plain and simple!
Everybody should sit back and ask themselves if they think they are getting a good return on the (let's just assume an effective tax rate of 25%) 25% that the feds seize from each of your paychecks. Sure, the feds provide me safety in the form of an army, the feds also had a decent amount of involvement in establishing our communications and travel infrastructure, and the feds provide the courts in which our law is based, but does anyone really think that the 25% of your money that the feds take in taxes each year from your paycheck is being spent wisely? Compare that to the roughly 7% effective tax rate that the State takes in and what the State provides- education, roads, police, etc.
