And how did the process start? The poverty situation in the better off countries didn't start improving because of magical fairy dust.

One end pushes the other end, sure, but you've got to start it somewhere.

People and politicians took action and improved laws, businesses still kept going and the cycle repeats upwards.

I don't see that happening in the US. I don't mind if the change isn't minimum wage (not going to happen in America), but at least do /something/ positive.

Something must be done? By people & politicians? This is the best way to fight poverty?

I agree that it isn't "magical fairy dust" that increases wages. What do you think it generally is?
