The employer just like the Zimbo is not willing to pay taxes. For reason well known, he would be deported once his whereabouts is known. However, the greedy employer deducts tax from his pay. It's either you work illegal or you starve. The other option would be to go back home before your ticket has expired.
Home is home sweet home.
But with the current situation it leaves much to be desired. One would opt for any kind of work to fill his belly. And the other form of entertainment, which they get, is sex. One person who just returned from UK told me that there's nothing else there except bhawudi. It clearly shows how people are depressed over there.
