I keep hearing that.
Ive been involved in various aspects of construction for 35+ years. (Framing, roofing, plumbing, painting and electrical.) I havent seen anyone making minimum wage since the mid 1970s thats when I apprenticed with an electrical contractor. Now youll make anywhere from $28 - $45 per hour, depending who you work for and what youre doing.
Not a single $5.00/hr job Im aware of. Helpers start out at $10.00. Thats for a live body with no experience whatsoever.
Construction work in the SW wouldn't pay anything close to that --- but maybe in some parts of the country they pay that. No one pays an illiterate unskilled immigrant that kind of money and full health insurance benefits --- the whole reason they do is to pay dirt cheap and let the taxpayers subsidize them.
