America needs an ineffective president. That's much better than an effective president that's going to go to war with Russia, that's going to push for the Trans-Pacific Partnership, that's going to protect Wall Street, and that's going to oppose neoliberal austerity. I would much rather have an ineffective president than someone who's going to do these bad things that I fear is going to come from Hillary and the Democratic Party.

We're living in a world that's divided into two economies: the economy of the 1%, and the economy of the bottom 99%. I guess you could be more "centrist" and say the top 10% versus the bottom 90%. But there's definitely a stratification at work here.

As you have to pay more interest and amortization on what you owe, you're left with less and less money to buy goods and services - unless you borrow even more and go further into debt.

From 2008 to 2016 all the growth in the American economy, all the growth in national income, was earned just by the wealthiest 5% of the population. So they got all the growth. 95% of the population didn't grow. If you can get a flat tax or other lower tax, as Trump is suggesting, then this richest 5% will be able to keep even more money. That means that the 95% will be even poorer than they were before, relative to the very top.

I think something like three-quarters of American currency is held abroad, by drug dealers, by tax evaders, Russians and Chinese. Other people think that they want to protect themselves against their own currency going down. When you have 75% of the currency and even more of the high-denomination $100 bills held abroad, you wonder whether these are people we really want to pay. If you get rid of the $100 bills, its foreign holders will be the main losers.

The banks' product is debt. They try to tell customers that "debts are good for you," but the customers can't afford any more debt, so there's no way the banks can continue their current business plan.

The aim of academic trade theory is to tell students, "Look at the model, not at how nations actually develop." So of all the branches of economic theory, trade theory is the most wrongheaded.
