Most of the old generation I know stayed (they say they are too old to re-commence), but most descendant from Italian, Portuguese, Spanish ancestors have one back to their great grandparents countries or somewhere lese in Europe.
Most europeans who came to Venezuela after WWII became a powerful upper-middle class, owners of businesses (restaurants, supermarkets, bakery stores, shoe stores, etc). Most of those business stopped being profitable under the current crisis. Some of them just chaged their line of business, but still (their children became the object of threats and kidnaps; with the money they had they were better off somewhere else)
