We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Robert Reich is re-hashing the idea that the greatest benefits of tax cuts have gone to the wealthy. That's largely because he's using the distribution of cash as his basis.
The question of whether tax cuts and resulting economic activity have benefited most Americans lies in standard of living changes. Nearly all Americans will agree that their standard of living has improved since 1981. Cell phones were ridiculously expensive in 1991; they're disposable now. The Internet charged by the hour in 1995; now it's $40/month for me at least, and unlimited and high-speed. Entertainment options are numerous and cheap. Decent clothing is very reasonably priced. Most of what makes up a decent standard of living is more readily available for less labor (real cost) than before, and much of what we want now didn't even exist before those tax cuts.
Low tax rates make the wealthy more productive and increase the share of total taxes that the wealthy pay. Statistics back this up. Low tax rates also help make the economy more productive and the rising tide does lift all boats, in spite of Reich's inability to see this.
Of course other factors affect our standard of living and tax rates are only one item, but they are very important. When Robert Reich tries to shaft the rich, he always winds up shafting the poor and the middle class far worse than he does the wealthy. When he cuts into their wealth, it comes from their excess. When he cuts into mine, it comes from things I can really use. When he cuts into mutual funds that support charities, he harms the poor greatly. He steals the widow's mite.
