Einstein was also a dedicated socialist. Intelligence doesn't always translate to wisdom.
Nevertheless, it is necessary to remember that a planned economy is not yet socialism. A planned economy as such may be accompanied by the complete enslavement of the individual. The achievement of socialism requires the solution of some extremely difficult socio-political problems: how is it possible, in view of the far-reaching centralization of political and economic power, to prevent bureaucracy from becoming all-powerful and overweening? How can the rights of the individual be protected and therewith a democratic counterweight to the power of bureaucracy be assured? …Once a “planned economy” is in place, it cannot be. Totalitarianism is inextricable from socialism; it’s part of the definition of socialism. People like Woodrow Wilson knew this; that is why he called socialism and democracy “one and the same” and pointed out the fact of the ideologies (ideology?) being antithetical to personal rights and freedoms.

This reminds me of a scene in “Independence Day,” where the guy who plays a White House top level person says, “I’m not Jewish.” When they were praying. The Judd Hirsch character says, “Nobody’s perfect.” LOL!
Even Einstein must have had faults.
