True, a proper accounting would tell you that providing property safety is a small proportion of the overall expenditure.<p>A somewhat similar argument can be made against minimum wage: even if it works perfectly well, it&#x27;s people shopping at Walmart that pay for the increases compared to market wage.  People shopping at Walmart are probably poorer than the national average, so why not make the overall population pay in eg negative income taxes or a basic income to help poor Walmart employees.  (A slightly more sophisticated argument would yield a similar conclusion, even if Walmart&#x27;s stockholders were bearing the difference between market wages and minimum wages.)
