Eistein's disgraceful past nullifies his credibility as a scientist.
"An investigation was conducted by the FBI regarding the famous physicist because of his affiliation with the Communist Party. Einstein was a member, sponsor, or affiliated with thirty-four communist fronts between 1937 and 1954. He also served as honorary chairman for three communist organizations."

Not sure why you posted this in the "spirituality" section, but as far as the pure ideal of communism goes, it has philosophical/spiritual merits. Even the Bible boasts some communist theory, as in shared property. To wit...this is from Acts 4:32-37...
32 "All the believers were one in heart and mind. No one claimed that any of his possessions was his own, but they shared everything they had. 33 With great power the apostles continued to testify to the resurrection of the Lord Jesus, and much grace was upon them all. 34 There were no needy persons among them. For from time to time those who owned lands or houses sold them, brought the money from the sales 35 and put it at the apostles' feet, and it was distributed to anyone as he had need."
That passage depicts a religious communal setting, but the ideal behind it is pure communism. And in fact, historically there has been a movement called "Christian Communism", though it's not well known, as most people assume that communism and atheism go hand in hand. But this is not necessarily so.
Someone once wrote a book suggesting a blend between Zen Buddhism and Communism, further proposing that this would be the ideal future for humanity.
It wasn't all that far-fetched, either...
As for Einstein, during his initial period of interest in this ideology the problem was not communism, the problem was fascism and an insane German dictator.
