Because inter-generational inheritance is the key contributor to creating a "useless class" similar to the slack-jawed English aristocracy. America had such high-tax laws in the past precisely because the Founding Fathers desired to avoid creating an embedded aristocracy.
As a minor point of information, the English aristocracy is probably a poor example to utilize here, as the English aristocracy were from childhood educated alongside the English gentry. This quirk of the English public schools system which you often must hear me criticise for its stifling effect did however possess one certain advantage in its early years; the English aristocracy, and I would certainly extend this to the Scottish, Welsh and Irish aristocracy, engaged in the exact same pursuit of professional accomplishment as their peers in the gentry. Hence the saying that Britain was a nation governed by shopkeepers, hence why British history is full of scientists, writers, engineers, bankers, officers, captains, statesmen, philosophers, administrators, businessmen and artists who weren't sponsored by aristocrats, they
were aristocrats.
The inverse is also true; conspicuous consumers who flaunted lavish spending and idle days to vaunt their wealth, majesty and general uselessness, were no longer confined to the realm of royalty. New money unburdened by notions of stereotypical British good manners and empowered by two centuries of global dominance were capable of cultivating and exporting a culture of horrendous excess throughout the world. I am reminded of one anecdote in London where a pleasure garden had an architect on hire in perpetuity to continually refurbish the garden ever week in order to please its patrons. It is no accident that Britons would invent
flexing at the same time as
multiple financial scams and financial bubbles which would leave millions impoverished and a handful with millions.
While I do agree with you and your founding fathers; where you escaped aristocracy, you created financial dynasties and far worse -
