: I am an undergraduate student who is writing an essay on the practices of multinational corporations in third world countries. If anyone has any information about wages, working conditions, etc, it would be of great help to me.
You might want to have a look at John Pilger's 'hidden agendas' (1998).
: Also I need to get some opinions on these questions:
: - why should corporations feel any ethical obligation to their workers?
Well most obviously it is a question of morality, that you should not viciously exploit your fellow human beings in order to make a profit for yourself. I think it was Kant who said something like human beings are an end in themselves, not a means.
: - aren't workers grateful for the jobs they have? (even if the wage is low, it is sometimes more than they would receive at another job)?
Every human being is entitled to a reasonable wage as a question of human dignity (See the UN declarations on human rights)...
Why should workers be grateful for the jobs they have when their superiors are making enormous profits off virtual slave labour.
: - if you buy products from large multinationals, are you implicated in the exploitation of others?
: - what can we do to prevent multinational corporations from treating their workers this way?
