Comment: Many comments here are, to me, very simplistic, based on a Trumpian idiot-ology, that sees things only in black and white. Either it's government intervention/control/command of the economy or it's let the private sector do it all, pure capitalism. This is not based on any evidence from anywhere in the world.

As the article says, "Historically, every country from Israel to the U.S. to China has always been led by public investments which directly create a new landscape. The business community reacts, gets interested. And then if you add some tax breaks, that will increase the marginal spending but it won’t make them do what they wouldn’t have done anyway. So that’s [why we need] additionality, getting firms to do what they would not have done anyway. In countries like Canada, there is too much reliance on indirect tax breaks that just make the companies richer. The point of policy is not to increase profits, it’s to increase investments."

This argument is grounded in the real world.
