When Thomas Paine's book, "The Rights of Man", was published in 1791, it was a best seller and one of the most borrowed books from British Libraries. It touched a raw nerve with the underclass in British society as well as the altruistic, benevolent members of the middle and ruling classes.
Paine's imagination exceeded his knowledge (hence why I like Einstein's quote) and he became one of the most radical thinkers of that era in his pursuit to eradicate grinding, endemic poverty through social justice. He campaigned for an interventionist programme of welfare provision including healthcare, old-age pensions, marriage allowances and maternity benefits to be financed by the redistribution of wealth/taxation. Paine's imagination and intellect forged the social framework that laid the foundation for the work of philanthropists and eventually led to the formation of institutions like the NHS.
Left to the handful of benevolent capitalist, we would not have the welfare system that we take for granted today. Indeed the rich liked the status quo because power was concentrated in their little niche group and they controlled government.
Thank heavens for the likes of Paine.
