Boy, this hits home!
The plumbers, electricians, tuckpointers, carpenters, and heating contractors we use are all eastern European immigrants. Some of these folks have built very large businesses and have become very successful. It's something else to listen to them talking about the streets "paved with gold in the USA".
What are tuckpointers? Never heard of that trade.
In fact, we had to fix a couple of slow-flowing sinks recently and the plumber came from Russia. He spoke almost accent-free English and told me that there's always business for plumbers, even when certain business closes because they need plumbers to make sure all the water is properly shut off and all the plumbing is in order for the next client that takes over the business site.
