you are right, we cannot blame a Cambodian farmer for their situation. I think that would make more sense to re-distribute wealth in the world instead of within our country. Taking money from a person in the top 1% and giving it to someone who is in the top 2% of the richest in the world doesn't sound like something the humanity needs.
A real left program would re-distribute wealth to other country in need.
But this need to be done on a voluntary basis, we shouldn't be force at the point of a gun to give our money to the government. Everyone has the right to choose.
