He served as the president of Lubin and Weinstock, "the largest department store in Sacramento, California", from 1920 to 1930.

[5] He was also a member of the Academy of Political Science, the Taylor Society, and the American Association for Labor Legislation.

[6] However, Paul Groth, a Professor Emeritus of Architecture and Geography at the University of California, Berkeley, suggests Lubin's intention in improving the living conditions of workers was to foster a more productive workforce.

[5] Moreover, Groth adds that Governor Hiram Johnson took Lubin's work seriously in light of the fact that the construction of the Panama Canal would inevitably lead to higher immigration levels from Eastern Europeans looking for work.

[1] Lubin died on April 15, 1936, at the Letterman General Hospital in San Francisco, California.
