@Frank Apisa,
"Unfettered capitalism" is, in my opinion, the wrong term. "Economic scam" may be a somewhat better term. For instance, our corporate leaders have the fix in by virtue of interlocking directorships, tightly-controlled boards of directors, etc., which allow many CEO's, et al., to make more than 1,000 times the compensation of the average worker in the corporation.
We use to have an ability-to-pay income-tax system, which is what graduated rates gave us. However, through lower top rates and a plethora of loopholes, people at the top are paying about 14 percent of their income. (The average worker is paying about 20 percent.) As I recall, Romney was paying at about a 14 percent rate on "reported" income. Of course, he had a lot of money shielded through use of tax-haven countries.
