To prevent the hereditary economic stratification and stagnation described by Jefferson.
To keep the American Dream alive, turning the ladder of economic success into an vibrant escalator that travels both up and down based upon individual merit, rather than an ill-maintained structure fraught with broken rungs.
You do realize that most American millionaires/billionaires are first generation millionaires/billionaires, don't you? Inherited wealth dissipates after a few generations. No need for a stratified, bureaucratic government to step in.
Government can give you nothing that it does not first take away, Willie Boy. I guess, like all Bolsheviks, you don't mind government taking away as long as it is from somebody else to give to you.
Invoking communism in the name of Jefferson.
In reading F.A. Hayek's The Constitution of Liberty, I did see that, while in France (which fits, I think with 1784), Jefferson became something of a believer in the "top down" planned egalitarianism of the French revolution.
However, the egalitarianism of the French Revolution formed the basis of what soon became socialism. It's in direct contradiction with the English tradition of individual liberty that most of us believe to be the basis of American freedom.
