Those who quickly dismiss Donald Trump's bid for the presidency are wrong. Rather than being a rambling account of a confused man's thoughts, his announcement is a testament to the vagaries of the capitalist system, and the unpredictable turns of history.

He is rather incisive in his opinion about the waves of migrants coming to the United States. I should know it, since I am an immigrant myself, although not necessarily one of those people that "have a lot of problems, and they're bringing those problems to us. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."

Perhaps some of these statements are right. On more than one occasion I brought some aspirin tablets from my overseas trips.
