Fair point. You have the right; it's just a dick move. End of the day, people who work at Wal*Mart made an active choice to work there; they weren't coerced or tricked. That's how the market works; employment is a compromise between employee and employer. The employee will only work for a minimal acceptable wage, and the employer will seek to maximize profit by offering the minimum amount they believe the job is worth. If the former value is less than or equal to the latter value, everyone is happy.
Of course, most employers (especially for high-skilled jobs) will pay more than what they consider the minimum amount of worth for a job, often to get that specific skill set (as it is valuable for the company in the long run).
