"We gave a number of possible reasons for why Hayek failed to speak out about human rights abuses. Given the string of countries that he visited on his trips (others of which also had authoritarian governments in place with their own human right records), and his visits to confer with former Chilean presidents on his second visit, it may be that he hoped autocratic regimes that practiced what he considered to be sensible economic policies would find a way back to liberal democracy. Constitutional constraints on unlimited democracy might provide the means to do so. Chile had adopted a constitution in 1981 that promised to hold a referendum that would allow a return to democratic elections in 1988. This was just the sort of result for which Hayek hoped. And Chile’s success, after following economic liberalization, set a good example."
