Absolutely.
Nation building is a strange euphemism. We've tried to come up with a way of describing the difference between two equally important types of infrastructure. With a museum or a sewage system, the challenge with those things is that they have future operating costs for a government. Taxes have to pay for them as time goes on. You'll get the bulk, the burst of construction, but then you have to have tax revenue to pay for those things going forward.
The thing about something like a power line or a road or an airport is that at a certain point the revenue it generates will be self-sustaining. A power line, in the long term, does not require future government operating costs. It's a tax revenue creator. You create business along the line. Vancouver airport doesn't require operating moneys; it actually pays money to the federal government. That's the difference. You have to do both kinds of infrastructure, because you need to enable the private sector to generate these revenues.
