I find posts like this one depressing. They're cynical and shortsighted.
The premise of such posts is that if people were aware of who was getting a tax cut they would be against it. Put another way: the premise is that everyone is purely motivated by self-interest.
There are two immediate problems with this line of thinking.
The first is tha it ignores how aspirational people are.i remember a survey from the 2000 election when Gore made the mistake of demonizing the top 1% repeatedly. The survey show something like 19% of people thought the were the top 1% and another 20% thought they would be someday.
The second problem is the whole "money for rich people = bad" argument. Some may ascribe to Reagenesque trickle down economics. Others may see that overtaxing the rich is ultimately shortsighted. Yet others may not get hung upon percentages and look at the absolute tax burden (iirc the top 1% pay ~40% of the tax burden).
Personally I just object to the tone of the rhetoric where politicians talk about "affording" or "paying for" a tax cut like they're giving away money. The reality is just that they're taking less money. Bit of a difference.
All of this is just "policy theatre" however. What the US (and most of the West for that matter) is facing a far bigger problem that the current systemis unsustainable and no politician wants to be at the helm when the music stop (to mix metaphors) with declining birth rates and increasing life expectancy.
