As MP Davies pointed out, we have seen declining capital investment over a long period of time and over multiple different tax regimes. We're not tax experts, so we're not going to evaluate any one particular measure.
What I would say is that there are really three things that go into productivity. There's labour and there's capital intensity, and then there's a multiplier in terms of how effectively we use those other two things. Our productivity problem spans across those things. Capital intensity, capital investment is one of those things, but we have room to improve in all three areas.
