Roma intelligentsia agitated unsuccessfully for inclusion of the Romani People in the 1968 Constitutional Act No. 144, and they remained the largest unrecognized minority in Czechoslovakia. Policy makers have found them a conundrum. The Roma population combines continued high rates of crime and illiteracy with a cultural system that places low value on regular employment. According to Czechoslovak Life, in 1986, "the customs and thinking of the Roma population are somewhat different." A 1979 article in Bratislava's "Pravda" asserted that the crime rate among the Romani population was four times the national average. The author went on to call for "the incorporation of all Gypsy citizens of productive age to the working process" and to decry the number of Roma "who constantly refuse to work". A large number of Roma were involved in the black market.
