The article presents a diagnostic assessment of the political and economic system transformation process in Poland. The author expresses an opinion that Solidarity as a mass social and political organization played a significant role only in the destruction of communism but not in the creation of a new political system. Its main leader, Lech Walesa, did not allow it to do so. And it was substituted in that role by the conservative - formerly communist - power after it had eliminated the orthodox communists' fraction. In co-operation with the Democratic Union and later the Union of Freedom, and Lech Walesa himself, it substantially contributed to the creation of a new post-communist system. In such conditions the economic system could not be formed following the model of fair capitalism but political capitalism based on the principles of pseudo-liberal ideology and propaganda and a contemptuous treatment of the academic science of liberal-market economics. The article also presents two forecast scenarios of future changes of the political system.
