1) Alex Jones is awful.
2) Infowars is not a good source of information, to say the least.
3) Paul Craig Roberts is NOT a "well-respected economist".
4) I know _Andrew_ Roberts professionally. He is a smart and wonderful guy, but he's also very bearish/pessimistic by worldview, so I would calibrate your opinions appropriately. Additionally, as someone working for a securities firm, he's probably inclined to let financial market sentiment and the dire state of the investment/banking community color his economic worldview.
5) I think the caution about the wisdom of economic forecasters in general, and those from Wall Street in particular, is warranted.
