It's 'pay me now in price' or 'pay me later to the goverment'. Knocking down the domestic payroll makes the company more profitable but is a loser for the population in growth of government [have we noticed?] . The government makes up the difference in building safety nets plus the social costs of family degeneration.
"Penny wise and pound foolish is no way to go through life" to paraphrase Dean Wormer.
That is only true if every employee Wal-Mart hires would have otherwise been working at a far higher pay scale without Wal-Mart. You'd have a hard time making the case that this is true with any Wal-Mart employees -- let alone all of them.
The "burden" that Wal-Mart places on taxpayers is a myth, and I'm surprised at how much traction this myth has gotten even here on FreeRepublic. It's not as if Wal-Mart builds a new retail store somewhere and imports welfare cases from all over the country to work there.
With thinking like that I guess you support raising the minimum wage to a "liveable wage".
