Everything that gets done by humans as a group requires humans as a group to do it. There will always be free-ridership and people who get more out than they put in. Should we then say “fuck it” and climb back up in the trees? Go back to the caves because the trees were a bad idea? Where does this regression end?
Surveys and studies have been conducted that show that investment in education yields benefits far beyond the dollars invested. Studies have also shown that barrier-free healthcare yields better outcomes for the vast majority of people living in a system. That these benefits translate to better productivity for more years for more people.
Only stupid people argue against investments that profit everyone including themselves. Even those people who object to lazy people getting free stuff.
