I tell you what,those Mexican roofers can get that old roof off and a new one on in record time. When you have the fat white guys do it, it takes for frickin ever.
I got a painting bid from somebody who was from somewhere in SA and I got one from an overfed white guy and the foreign guy was 2K under the other one, got in here and got that wall paper off and the walls painted in record time. Worked from 8 am to 6 pm every night.
I have more house than energy, so when it gets really dusty I will call a cleaning service. 25 years ago it was black ladies who resented me for hiring them. These days it is Mexican ladies who can clean like nobody’s business.
So, if they have a good work ethic I am all over it.
Here in CA where we have millions I've seen all kinds of migrant labor, from busy and quality minded (increasingly rare) to lazy, inexperienced and dishonest. There is no one word to characterize them.
