I have very specifically not argued that. I have in fact said I think we can and should reduce the rate of increase, which maps to the first derivative. You are arguing for making that first derivative not just smaller but negative, and in fact a negative number with a very large absolute value over a short period of time, and you don’t really have any evidence for what that would do to health care delivery and to the U.S. and global economy, because there is no precedent for it.
No. This is either incredibly naive, or disingenuous.
Here’s what I would consider a better analogy, in part because it actually does involve decades of growth (managed vs. not) and public policy.
Are you familiar with the Urban Growth Boundary (UGB) in Portland Oregon? The UGB was a wonderful progressive policy begun nearly a half century ago. The result has been an avoidance of the kind of sprawl seen in other metro areas. Areas outside the UGB line are still green, and the areas inside the line are more carefully utilized, avoiding the kind of “hollowing out” we see in a place like St. Louis, where there are a lot of abandoned warehouses and weedy vacant lots.
So let’s imagine the electorate of the state of Missouri became progressive enough that they wanted to emulate Oregon (this is a stretch as things currently stand, but let’s just go with it for the sake of argument). What you are doing is the equivalent of such a Missouri government declaring “We want to make St. Louis just like Portland, so we’ll just ‘do what they do’ and it will be all taken care of, simple as that.”
But of course in reality you could draw a line on the map around St. Louis and it wouldn’t magically eliminate all the subdivisions and strip malls outside that line, not to mention all the highways and surface roads and other infrastructure. Would you go in there and tear all that stuff down, bulldoze it, and start planting trees in its place? Where would all those people go? What about all the jobs at those shopping centers? Who is going to pay for the massive cost of trying to retrofit a sprawled-out metro area to make it like Portland?
What I would argue is that you can put a UGB around the extent of St. Louis’s current metro and in so doing prevent it from being even worse in another fifty years. And you can work on incentives to make people “fill in” residential space inside that UGB, maybe even slowly offer incentives for the furthest exurbs to convert to being “greener”. But you can’t just “do what Portland does” and get the same thing now that they only have as a result of a long process of making smart urban planning choices since 1973. In a way, it would be kind of unfair if you could, right? Portland and Oregon kind of deserve to have something better as a result of good foresight, don’t they?
