 Lugo's government was praised for its social reforms, including investments in low-income housing, the introduction of free treatment in public hospitals, the introduction of cash transfers for Paraguay's most impoverished citizens and indigenous rights.Some of the initial results after the first pink tide governments were elected in Latin America included a reduction in the income gap, unemployment, extreme poverty, malnutrition and hunger and rapid increase in literacy.The decrease in these indicators during the same period of time happened faster than in non-Pink Tide governments.
