Reverchon said that Piketty's effort was worthwhile at a time when the left is mindlessly attempting to bring too many issues together under the same umbrella—"environmentalism, reformism, feminism, post-colonialism, anti-capitalism".

Piketty calls for the state to increase access to quality health care, education, employment through the progressive implementation of taxation on the most wealthy.
