Just to give another view--
- Landed gentry- do nothing for their money, just collect rents from farmers , unlike industrialists who create a manufacturing business, or financiers who identify promising businesses and risk their capital investing in them them.
- Merchant seafarers - liberals today would call them 'globalizers', buying goods for very low prices where labor is very cheap and selling them for huge profits elsewhere.
"Both the Roosevelts and the Delanos were prosperous merchant families who had derived much of their fortunes from seafaring. As a landowner with a Hudson River estate, a man from a family that moved easily in the Edith Wharton universe of Knickerbocker society, Roosevelt approached economic problems with different preconceptions from those of the industrialist or the financier on the make."
