Do you have some sort victim complex, no one mentioned anything about "erroneous posts". You did however put up statistics, if you want to call them that which show a bunch of charts that anyone with Excel could have made.
There are thousands of examples of real people who have seen their wages plummet while others have had to train their cheaper replacements. Again it's about those export jobs, import people policies, aka as the "willing worker, willing employer" line.
Many post on this site. I tend to believe them rather than generic charts that any third grader could have made up.
You're absolutely right about how anyone could make the simple charts I linked-- all we have to do is copy public stats, paste, and mash the 'graph' icon. This "thousands of examples" you mentioned could make a nice graph too --if only they existed.
To paraphrase Mark Twain, always tell the truth, there's less you have to remember; or make up for that matter..
