You missed the point.
The company hires the illegals BECAUSE THE COST OF UNION CONSTRUCTION WORKER'S WAGES ARE TOOOOOOOOOO HIGH. Don't tell me union workers won't do this work.
It's just that company's are trying to make a profit - you know - a profit - for being in business. Why wouldn't a company want to hire illegals when it lowers their expenses of doing the job.
And .. it's not just wages, but wages and benefits' costs which employers are trying to keep lower. Unions keep demanding higher wages and more benefits, which prices UNION WORKERS about what some small construction companies can afford.
Where's your proof that construction companies are unable to make a sufficient profit while paying union construction worker's wages?
You're building an argument on a false premise.
What's the hardest manual labor job you've ever done? How much were you paid to do it and why aren't you still doing it?
Why don't you have any respect for the skilled tradesmen and the craftsmen that work in these construction fields?
It's snobs like you that are the reason that many socially and fiscally Conservative union members don't trust the Republican Party.
I'm not a union member, but there were many injustices visited upon employees in the past by their greedy employers that led to the formation of these labor unions.
There were and still are unscrupulous, unethical employers that would work their labor force to death, for barely enough to stay alive, and laugh all the way to the bank, while doing it.
The jobs these employers offered amounted to little more than indentured servitude or another form of slavery.
It appears you'd have the inclination to be one of those employers, if you owned your own company.
