I agree with your comment on Capitalism, and I've not doubt that the Puritans would have ideally liked to have seen a nation where only their brand of Christianity would be taught. But I think they were more practical than that and the reality was that if you disagreed with them then you were asked to leave their colony.
I do not agree that the majority of the Founding Fathers believed that non-whites on non-landowners were not created equal. They had to deal with the same democratic hindrances that arise with conflicts of agendas. Compromises had to be made in order to reach the primary objective of setting up a working federal government. The truth is that protesting against the powerful system of slavery was not the immediate concern at the time. The landowning requirement had more to due with the level of education and vested interest of voters. Back then, the majority of the population had little understanding about politics and little resources to keep abreast of issues. The political issues of the day varied significantly between the colonies.
And you can credit those early Puritans for setting up the system of education in the U.S. that fostered the growth of literacy and higher education.
