I went to Walmart once, I won't go back.
That said,
So a lot of 'adults' (ie, not students, for example) live on a Wal-Mart wage.
So how many people survive by shopping at Walmart. Yes, a lot of what they sell is junk that wears out three times faster, but for people going paycheck to paycheck its all they can afford. And no, I don't think making the paychecks bigger by legislative fiat is the answer, because the price of everything will also go up.
Let's see all the people belly aching about Walmart start their own department store so they can show us how easy it is.
