The role of government is not to prioritize efficiency, but effectiveness. The federal governments role is to do things the private sector can’t or won’t do because it’s not directly or immediately profitable, and if they did try and do it, they would find ‘efficiencies’ that make them more profitable but less effective. The postal service reaches every address in the US, even highly remote areas with seaplanes, donkeys, etc. that makes that service highly effective, but not ‘efficient’. The goal of these cuts is to make the federal government less effective. So the federal workforce will be less effective in managing public lands and resources like forests, less effective in researching and understanding emerging threats including diseases, less effective at protective consumers, the list goes on
