It is called a combination of racism and sexism. Neither have any place in America. Here, we pay people an agreed rate under United Farm Workers contract. We harvest grapes in June, hay in July and August, Corn, Soy, and Sorghum in September, and timber year around. We also plant new trees year around. All our people are covered under Labor and Industries (we pay dearly for that but it is the right thing to do) and we have yet to suffer an un-planned layoff.
In the winter, we tend vines, rack wine, and do whatever else needs to be done. There will always be horses to feed for the hunting outfitter service my husband runs, gear to maintain, and lots more.
But we make a point to pay fair and play fair.
Obama should also.
But he never will. It is entirely a matter of poor leadership.
