I haven't done the calculation you mentioned in that exact way, but let me reinforce the point I think Governor Macklem was making: The economy is operating at capacity. If governments are increasing their spending at a rate that's faster than the productive capacity that the economy can grow, then it's making the job of monetary policy more difficult because the economy is running too hot.
The other thing that's important to mention is that, if you're increasing your share of GDP that's going to the federal government, something else has to shrink. Right now, we are in a pretty severe housing crunch. We need at least to be maintaining the share of our GDP that we are putting into housing or the shortage is going to get worse. We also need to raise the share of our GDP that's going to into capital investment, because it's too low. Capital per worker is falling, and that's why productivity is falling and living standards aren't rising. It's a problem if the federal government is projecting its share of the economy that it uses directly to increase...and it's a problem if the rate of growth in government spending is exceeding what the economy can produce.
