To continue the last post (hit reply early... haha whoops).
Let's look at Income Growth now:
This gives much of the same story as the GDP growth.
We see some small growth in Median income, a measure of how the avg. american is doing, when the top-bracket taxes were cut in the mid-1960's and the 80's, however we see income decreases after the the late-80's tax cuts, and see some increase after the tax increases of 1993 (clinton-era). 1974 had the worst median income decrease, with a tax rate of 70%, but it also saw the highest median income growth. No correlation again.
Now let's look at wage increases:
Surprise surprise, we have mixed results again!
Growth in hourly wages did increase in the 80's following the reagan tax cuts, though it took two years for that to happen... but, just like GDP and Median income growth, they decreased following the late 80's cuts, spiked upwards after the 1993 tax increase.
Wages grew at a good rate (1% or more, usually more) all throughout the time when the top tax rate was 91%. In fact, it wasn't until 72 (tax decrease) that the growth was less than 1%. If we look at the time that the tax rate was 50% or less (19 years), we see that 8 of those years saw an increase of less than 1%.
Now let's look at job creation:
Negative means decrease in unemployment (in essence, job creation). So, even though the top tax rate goes down, we see unemployment remains essentially the same. Three of the four largest increases were when the top tax rate was 91%, the fourth being the largest, happened when it was 70% in 1975. The mixed results speak poorly for those who see cutting taxes for the rich as a way to incite job creation (significantly).
So, can you tell what our conclusion is yet?
Overall data strongly refutes any arguments that cutting taxes for the richest americans improves economic standing of the lower or middle classes or the nation as a whole. To be sure, everything in these graphs are dependent on MANY MANY factors, not just tax policy. However, what these do show is that any attempt to stimulate growth by cutting taxes for the rich (only talking rich here), HAS NOT worked over the past 50 years, so why should it work now? Why would it work in the next 10?
Put simply: Bush's top-bracket tax is ineffective, and will not cause any growth. Unless, of course, you're talking about the growth of the deficit.
