And of course the immigrant laborer is perfectly willing to work for as high a wage as he/she can get. And they do hold out for higher wages depending on the given circumstances.

It is of course the employers who depress wages if they are able to, given the conditions of the labor market.

It is often the illegal status of the immigrant worker that in part undermines their bargaining power, but that is the moral fault of the conditions of capitalism and its dehumanizing divisions of workers into legal/illegal. A sort of aparthied if you will. But it is simply absurd to blame the victim for not having the social and poltical resources to demand a higher wage.

(I have read and commented here before, but now I have recently started a new blog and new ID. I am going to continue this line of thought over there, stop by later if you like. Once again good post and thanks for getting me started)
