Yes, there are families in Florence, England and other European countries and cities who have enjoyed unbroken dynastic wealth over several hundreds of years. But this doesn't prove that Europe is more or less equal than the US. The US has only existed for ~2 centuries. In 1870 the US surpassed the UK to become the world's largest economy, and remains so. So there's only been 2 centuries or less for dynastic wealth to form in the US, as opposed to ~10 centuries in Europe.
