Our FFs did not want family dynasties so rich and powerful that they could challenge the power of the federal government  -  in other words, kings or emperors who would not be subject to the same laws and restrictions, or have more freedoms than ordinary citizens.   They heeded the lessons to which their parents and grandparents were exposed in the Old World.  Let the rich be rich, but not take over the government  -  imperfect as it is.

Besides, little of this wealth would have been available had not the government (that's right  -  us, the taxpayers) instituted the Articles of Incorporation, and other financial advantages which allowed businesses to accrue artificially enhanced incomes.
