Please know that in periods of "high personal tax rates" business owners declared their income through their companies thereby lowering their tax rates. You would have a company car, company vacation, company dinners, you can even make it company policy to pay for the employees children college education, etc... This is the same reason any comparison of income equality over time is meaningless. Since income was declared through different avenues.

To understand the tax implications of economic growth you have to look at the tax payments as a percentage of GDP as well as compliance costs. In the US tax payments have held steady at about 18% of GDP since WWII until recently. People hunt for loopholes no matter what. But when rates are low you don't have to look for loopholes, so you can deploy your capital more efficiently. Thus generating economic growth. This is why tax cuts often stimulate large economic booms. Capital that was sitting in say tax-protected muni bonds will move into the market and be deployed for business expansion and thereby hiring.

There's so much evidence to the contrary of this article, even Obama's own counsel of economic advisories share the view that tax cuts stimulate economic growth. Christina Romer, his former advisor wrote a paper on the subject. What they do is look at country around the world to collect more data points for a better regression analysis.

Also note that when you say "tax cuts", not all tax cuts are made equal. For a tax cut to be effective it needs to change long-term behavior. So credits and such have a near zero or negative effect while rate cuts have a positive effect. The most beneficial being capital gain rate cuts (ie every time they have been cut, revenues from the tax have increased), corporate, and then final income tax rate cuts.
