The benefits we receive are phyrrhic victory at best. Yes, I’ve seen the farms and the construction sites. I’ve also seen the nannys and residential gardeners.
The net result is they are actually taking more out through the use of our infrastructure than the benefit we receive.
As for unemployment, the numbers have been twisted in so many contortions for political purposes that they barely represent anything.
Now, if we truely can’t live without them, then we should make them citizens and move on. If not, then allowing their exploitation for the benefit of the few, the business owners.
