I fail to see how a worker making $7/week or month will be able to afford a washing machine in the near future. Presuming the wage 30 times higher and a savings rate of 1$/week in 100 weeks they will be able to save $100. However such a savings rate is vastly higher than one may expect. Look for rates more like $.10/week. The lower paid worker is barely managing to subsist. For them a luxury might be some occaisional protien or more than a one room hovel without running water and electricity. More likely they are living in a Chinese dormatory and any privacy is a luxury.
I think, and I could be wrong, the washing machine miraculously will not cost the $500 it costs here.
I used to live in Europe. I would buy Kellogs Nutri Grain bars. I would pay $2.00 for a box of them. I come home and a box of Nutri Grain bars can set me back $3.69.
