Warren is ... a pyromaniac in a field of straw men: She refutes propositions no one asserts. Everyone knows that all striving occurs in a social context, so all attainments are conditioned by their context. This does not, however, entail a collectivist political agenda.
Such an agenda’s premise is that individualism is a chimera, that any individual’s achievements should be considered entirely derivative from society, so the achievements need not be treated as belonging to the individual. Society is entitled to socialize -- i.e., conscript -- whatever portion it considers its share. It may, as an optional act of political grace, allow the individual the remainder of what is misleadingly called the individual’s possession.
The collectivist agenda is antithetical to America’s premise, which is: Government -- including such public goods as roads, schools and police -- is instituted to facilitate individual striving, a.k.a. the pursuit of happiness. The fact that collective choices facilitate this striving does not compel the conclusion that the collectivity (Warren’s “the rest of us”) is entitled to take as much as it pleases of the results of the striving.
