what is/was the name given to families that only got rich because they got lucky in the industrial revolution? My mum and I were trying to remember and even though its trivial, its annoying us. But I can't rmember if its just a name given to them by aristocracy at the time or in the future or both.
That's it, newly rich.
There's also Parvenu. A newcomer to a social class. Their money would bring them there. And then there's 'Counter jumper' someone who has progressed from selling at one side of the counter in a shop to being a customer at the other side.
