Thanks a lot for this article. It helps me to understand this theory which is simple and yet hard to understand.
I'm not sure to which extent I'm convinced, but I think it's important to keep an open mind. The ECB and the US Fed have created massive amounts of money since 2008 and yet economies have stagnated with low inflation, which might validate some views of the MMT.
Do you have plans to write more articles on this topic? Being French, I'd be interested to understand what MMT economists say about the Euro and the ECB. It would be very relevant to the current debate in Europe about the ECB buying back some of the national governments' debts, and even about cancelling some of it.
