Tito's own ideology became less clear with the pressures of various nationalisms within Yugoslavia and the problems posed by the 1970s Croatian Spring. In terms of economics, Yugoslavia became somewhat closer to a free-market, neatly separated from other Socialist regimes in Eastern Europe (and marked by a permissive attitude towards seasonal labor of Yugoslav citizens in Western Europe). At the same time, the leadership did put a stop to overt capitalist attempts (such as Stjepan Mesić's experiment with privatization in Orahovica) and crushed the dissidence of liberal thinkers such as former leader Milovan Đilas while it also clamped down on centrifugal attempts, promoting a Yugoslav patriotism.
