If you read the OP, 'The average warehouse worker at Walmart makes just under $40,000 annually, while at Amazon would take home about $24,300 a year," CNN reported in 2013.' So how can you include Walmart in your statement? Think about that: the AVERAGE warehouse worker at Walmart made 40k in 2013, 5 years ago! That's almost $20 an hour and pretty good money for people driving forklifts and pushing skid jacks.
Not only that but Walmart increased its minimum starting wage and gave $1000 bonuses to employees just this January. Walmart also does not have a parasitic relationship to the U.S. Postal Service.
That you made this political is not surprising in the least. After all, it was clearly a political statement.

You made a very good point, using only evidence in the article to highlight the hypocrisy in the visa system. Obviously we don't need to import job seekers who cannot have qualifications beyond what every American computer science graduate has.
For positions which are not entry-level, one way that companies are getting their cheap H1B labor is by exaggerating the 'particular hard-to-find skill set', creating a combination that no one in the industry would actually have. But miraculously, the "consulting" company finds just such applicant overseas.
