No the Democrats support what you call ROE...or what everyone else calls Keynesian economics...because ITS WHAT WORKS and it WORKS EVERY TIME! Think WWII...it was a massive government spending and jobs program.
And Keynesian economics is why the third world could be so freakin' rich that they can burn money as cooking fuel, if only their dictators would realize that unlimited government spending on statues of the glorious leader was the recipe for prosperity!
If blowing other people's money on massive vanity projects worked,
every country would be rich,
One of the problems with Keynes is that our government is made up mostly of former state government officials whose accepted wisdom is that road projects provide an economic boon, which may have actually been true in Keynes day, but no longer.
In the early days of road travel, there weren't many good roads, and each one built brought more people and products into the larger economy, with goods shipped longer distances (where price differences could be greater), along with creating new businesses, tourism, gas stations, and changing how our communities were structured and operated. No longer tied to wagons, things changed. The effect was so profound that it's still burned into the brains of every politician, half a century after the secondary effects dwindled, and they still think road projects are the answer to every question.
There are serious flaws in such thinking. The first roads free you from local conditions, and traffic and economic activity boom. Subsequent roads and improvements are required to handle the increased traffic from the boom. It's similar to getting the first water line, gas line, sewer line, and electric line run to your house, profoundly changing your life forever.
But once they're run, then upgraded to handle all the appliances you bought, you don't need
more gas lines, sewer lines, and electric lines. Your first water line frees you from going to the well. The second water line just kind of sits there, an utterly useless and expensive addition that will never pay for itself. The first route to work, or Best Buy or Walmart, was a boon. Now the government is billing you for a fifth route to Best Buy and patting themselves on the back, as if you weren't buying a new DVD player because you only had four ways to drive to Best Buy.
On top of that, building roads hasn't seen many big efficiency improvements since the 1950's (road graders, bulldozers, and dump trucks haven't gotten a whole lot better at the task), while other investable sectors of the economy have seen massive efficiency gains. If you wanted a real return on investment that
didn't depend on kickbacks, would you put your money in networking, biotech, robotics, or grading and paving?
Finally, if infrastructure investment is so important, how come nobody in the government ever talks about upgrading our electric utilities, our private water utilities, our gas utilities, or any other private utility? They're all more important than roads, because you can drive a vehicle without a freshly paved new road, but without gas its going to take a lot of horses or sled dogs to haul semi-trailers to restock the stores.
