2. The point I was making was that increasing the share of the economy that is centrally directed doesn't make that economy run more efficiently. If you take a chunk of the economy out of where it was being allocated by the market according to market incentives, and give it to politicians, who allocate it according to political incentives, you haven't increased the effectiveness of that wealth, you've decreased it.
No, Republicans and Democrats both agree that they like getting credit in their home districts for big expensive projects financed by people other than their constituents.Conservatives and liberals both agree that our infrastructure is in serious need of repair.
Nor should you conflate the Trumpkin/Bannerites with Conservatives. Conservatives are aghast at things like a Trillion dollar "Porkulus II".The crazy thing was conservatives condemned Pres. Obama when he begged for billions in American Jobs Act (and to a degree, in the Stimulus bill) to go toward infrastructure rebuilding including those so-called "shovel ready" projects. But now many of these same conservatives are in support of federal spending for the same "shovel-ready" infrastructure projects.
