Crises in social systems are considered by analogy with phase transitions and the corresponding critical phenomena in «non-living» many-particle physical systems. We present two qualitative physical models: (i) a historical and demographic progress as a gradual condensation of economical domains with an improvement of living conditions, and (ii) the modern economical crisis as a result of a spontaneous «condensation» of assets in a free expansion of the U.S. economy in 1990th and 2000th, reducing a control over large business enterprises formed in this process. The first model explains the observed hyperbolic growth of world population in the I–XX centures A.D. without any additional assumption while the second model points to the analogy between the economic expansion with a drop of competition, and the expansion of gas into vacuum with a drop of temperature.
