What was one negative effect of the end of communism in czechoslovakia?

The biggest problem of ending communism in Czechoslovakia and dissolving the country into to separate countries in 1993 was the economy of both Czech Republic and Slovakia in the first years. It was because administrating one economy became administrating two separate economies. There were also some problems with ethnic groups (Romans), language and citizenship. However both countries managed to stand up on their own legs in a relatively short time.
