As it does with all private sector initiatives.
Look, I’m not saying government is always or even normally a more efficient producer of wealth than the private sector. I’m just pointing out that government provides many goods and services we would consider “wealth” if provided by a private entity. I see no reason why these same goods and services should not be considered “wealth” just because they’re produced by the government.
This is actually an argument to make government smaller. If it concentrated on those things only it can do, it could presumably do them more efficiently and produce more wealth in the process. Since it isn’t interfering with the private sector as much, the PS is also able to function more efficiently and generate more wealth.
Win/win. Except for those who think government spending and control is morally superior to spending by the private sector.
Maybe it is an issue of maturity. When the Interstate system was put in, it generated a lot of wealth. But spending on the interstate system now does not, it is a maintenance item that is important but it doesn't generate new wealth when we spend on it.?
