NAILED IT!  Especially since the Reagan years, companies have successfully lobbied Congress for the ability, and colluded with one another, to artificially suppress wages for all but the most top-level officers (i.e. THEMSELVES aka "job creators" (modern-day slave masters)).  Basically, if today's business owners, CEOs, et al., could endeavor to return to the pre-Reagan business model, where company profits were more equitably SHARED with their workers -- the people actually performing the work from which profits are made -- then a $20 per hour wage for landscapers would be downright affordable for commercial and residential customers alike.
