Why have Mexicans nearly replaced every single white manual laborer?

This has happened over past two decades, but really whenever I see anyone who is white doing any type of manual work, I have to take a picture with my camera. As it is like seeing a Tin Lizzy Ford driving down the street or some other type of antique car? Why this has happened? Are they that good of workers? I have seen them laying around on lawns taking a nap. Why?

Most whites would rather be doing manual work than being janitors

Because whites think manuel labor is the president of Mexico…

Just taking it easy you know chillin

I worked manual labor throughout high school and still work it right now in college to pay my tuition.

No They haven't. Not by a long shot.

Perhaps a siesta! The Mexicans I have been associated with are very hard working. They are hungry for jobs. Unfortunately, many Americans don't want labor jobs. They don't want a job that demands hard work. They want to make a lot of money without working for it. Very sad.

Nobody wants to mow a rich executives lawn for 25 cents a year

What happened to those white men? More social awareness needs to be made for white color hatred of blue collar. But, they run the social control campaigns. Its absolutely sick. It is not normal for American life to revolve around kids busting thwir busts in school to be something they aren't. Or, suffer for eternity. Fact is, white collar people are born that way. There gas been a rift since the beginning of time. They envy that these men can bulid things, are way better in bed than them.
I knew a man who could build a luxury log cabin, 5 bedrooms all by himself with a small team. He drank himself to death. Usually they are very musically talented too. That society takes all that for granted is sick.
We're all being hoarded into overpriced shoeboxes with no aesthetic beauty at all.

Economics. Take a business class. Business would use monkeys if they could. Don't worry. Very soon robots will be doing everything and then who will we blame?

Because it's the only way to keep the the manual labor jobs in the US Employing only white Americans to do manual labor costs too much; employers that don't hire anyone else usually end up losing money or having to close down or move to other countries.

And they are that good. Some types of farms produce only about 1/4 of the food without Mexican workers that they can produce with them.
