If you actually knew anything about Europe, you would never have written that nonsense. Roma people don't work in formal jobs. Many are drifting and some are "employed" by organised gangs who roam Western Europe begging. Many women are forced into prostitution by their own community males. The idea that Roma people form somekind of backbone of blue-collar work without which Europe couldn't survive is the most hilarious nonsense I've read in a long time.
This comes across like you are admitting to their poor socioeconomic situation and preemptively blaming their supposed moral and cultural inferiority for it.
Gypsies aren't some kind of ubermensch caring all of Europe. All the same they are a group of ethnically-defined undesirables used as disposable migrant labor throughout Europe. It's easy when those countries neglect to take census data of them, conveniently hiding labor data, human trafficking, and mortality rates in the community.
They get exploited by illegal non contract jobs, and being outside the formal labour market they are
. In Romania they're the cheap construction and mining labor. They're estimated to be the largest European ethnic group
All this illustrates a continuation of western love for racial enslavement, see the practice of Roma chattel slavery from 13th to 19th century (basically grabbing and chaining any Romas you found in the street), genocide by Nazi Germany, their better conditions and favored status under communism (see USSR movie
or the world's only gypsy theatre in Moscow) and their return to pseudoslavery today.
