The connections that Šik made at Mauthausen proved useful in his post-war political career. In the early 1960s he attempted to persuade the hardline president, Novotný, into loosening his rigid adherence to central planning, which had been crippling the economy. Šik, who by this point was an economics professor and member of the Communist party, wanted to bring market elements into central planning, to relax price controls and to promote private enterprise in the hope of kick-starting the stagnant economic climate. It was around this point that Šik was elected to the party's central committee and was made head of the economics institute at the Czech Academy of Sciences. Šik's reforms were launched in 1967, before Dubček came to power, but were heavily watered down by party apparatchiks who worried about losing control of the factories. The only palpable, and certainly the most popular, result of the reforms was the appearance of private taxis on the streets of Prague. In December 1967, at a party meeting that was a precursor to Dubček's coup a month later, Šik publicly denounced Novotný's regime. He demanded a fundamental change to the Communist system and a new leadership, two decades before Mikhail Gorbachev he announced that economic reform could not be separated from fundamental political change. By this point Czechoslovakia had the lowest growth rates in the Soviet bloc, whereas previously it had been the economic backbone of the Habsburg empire. Following Dubček's successful coup, Šik was made a deputy prime minister in April 1968 and he was the architect of the economics section of Dubček's action programme. Šik claimed that if his policies were followed then Czechoslovakia would be on an economic par with neighbouring Austria within four years. However these plans were never followed out after the Prague Spring was brutally ended in August of the same year by the tanks of the Soviet army.
After the Prague Spring
When the tanks rolled into Prague, Šik was on holiday in Yugoslavia. With the threat of arrest looming, he never returned to his homeland. Leonid Brezhnev and the Soviet Communist Party's propaganda machine singled Šik out for particular attention. In August 1968, TASS issued a press release calling him an agent of U.S. imperialism and "one of the most odious figures of the rightwing revisionists". Šik left Yugoslavia in October 1968 and moved to Switzerland. In 1969, he returned to Prague and tried to convince his colleagues but his views were rejected. So he returned to Switzerland where he became an economics professor at the University of St. Gallen in 1970. He held the post until he retired in 1990. After the Velvet Revolution Šik became an economic advisor to the Czech president but had no impact on actual economic policies. He became a Swiss citizen and lived there until his death.
