There is a lot gross assumption akin on intellectual bankruptcy in your post one does not know even where to start. First off, knowing what you know and trusting what your wife and relatives tell you about these "hopeless immigrants", it is amazing you still heading to Canada.
How more myopic can you get? Aren't you just lucky the Canadian authority are not as jaundiced in their view as you have displayed here to have allowed you in? Going by your gross generalization, you are going to be just another one of those potential liabilities on the system right?
What comparative information have you to suggest that any one of the so called "back loggers" would do worse than your lucky "fast trackers"?
That coming from someone who hasn't even stepped their feet on Canadian soil is the peak of absurdity. Dude, stop getting ahead of yourself you haven't even got a job yet let alone paying a dime in tax. Get off the high house, will you! Do you know what prejudice is even if it hits you in the face? By your logic, how much do you think you should be making and within what time frame before the Canadian system considers you a liability?
The irony of this is that you might be right about some people not befitting of coming to Canada and since fact and introspection appears not to be your strongest point, can I suggest you pick up a mirror.
Not interested in pointless back and forth with you, just want to point out a few things should you are interested in some introspection.
All the best and get some more knowledge before you head to Canada.
