Whilst I think it's very worthy to sign a petition I think you need to address the deeper issues. There are 4500 factories in Bangladesh producing clothes for the West. It's not just Walmart (Asda) it's all the multiples here. M & S, Tesco etc. So, if not you, if not your children, if not your grandchildren, who does rejoice in these cheap clothes? Do your children mend clothes, do they make do, do your grandchildren want hand me downs?
Society has changed. For right or wrong. Signing a petition make make you feel good but unless you and the generations below you change, nothing will.
I bought second hand clothes and furniture - my children point out, it's cheaper to buy new. Go figure
