In the US a couple of years back, many of the Hispanic families moved out. The workers were legal but many in their families were not. Then there was a labor shortage. Many of the fast food chains could not get workers for the $10 an hr, they were paying, so a wage war started, most went to $15, Panda Express went as high as $18. so they had to start paying more. Some were even giving out bonuses if they stayed on for 6 months. Even then many of the shops shortened their hours. The farmers couldn't get the field workers they needed because they could make more money doing easier work at the fast food shops. Now everyone wants to know why the price of food has gone up.
