Your statements are so ignorant, explains a lot about where you are on the totem pole. White, brown and black people have been competing for decades, price and performance are what matter in a free market economy.
I bid on large contracts and also sub out work on projects, I hire people that I know who can deliver within a reasonable price range. I could care less about what nationality or ethnicity they are. Good contractors are hard to find and harder to keep, almost all businesses operate this way. If any man walked into my office, instead of having their "business development" people calling and emailing me, to ask for work and I could determine in that meeting that he was ready, willing and able, I would break off some work for him immediately just to see if he can deliver. Is that really so hard for you to believe?
If you were smart..... you would direct your energy towards the border and the influx of unskilled cheap labor that devastates the manufacturing, construction and service industries, impacting ALL kids in their late teens and early twenties. I could go into great detail on the impact on first time jobs, developing work skills, developing connections, etc. but what's the point. Welcome to 2019 Lemming.
