The former is a very twentieth century notion. The identification of government with society (“we”) went hand in hand with the idea that government should have power in every domain of human life and co-opt or liquidate every competing authority like academia or media or church. Here, it’s that “we” the government should take over healthcare (although regulatory approval of a cancer treatment was cited as one obstacle) and fiber-laying instead of leaving those to non-governmental authorities. Carl Schmitt in the early twentieth century had a great term for such a totalizing government: the Totalstaat. It’s not clear, however, that a Totalstaat is actually a good idea. Governments have never solved many problems at all—-homelessness comes to mind—-and it’s not clear that a government seeking to expand its power into previously non-governmental domains will serve its own interests best by solving problems rather than by providing treatments that abate problems without solving them. Treating a problem expands a state’s authority while preserving the problem as a reason for further government action; solving a problem would end that authority by ending the reason for it. Winning a war, for example, used to remove the need for a standing army until the twentieth century saw the invention of a “cold war” and “war on terror” and a perpetual standing army to treat the unsolved problem of a lingering threat. It’s not clear that this increase in government power was a good thing.
Secondly, the idea that “we” (government) “know” the answers is hubris. The author claims that “we” know it would be good to send everyone to college for free, but is that actually best for everyone? Or does that just turn college to more high school, lower the quality of education, waste a lot of people’s time, slow down the creation of families and negatively impinge on demographic trends, etc? “Knowing” the solution presupposes knowledge of second-order effects, and people are generally very bad at that. Thinking that a total state “knows” the best solutions to problems is a good way to impose lots of (potentially negative) second-order effects without much recourse to do anything about it, since this total state has all the authority and no longer has competing authorities to check its hubris.
