Adam Smith, in his Wealth of Nations, in 1776 explained a possible way to reconcile the difference between liberalism and republicanism, or between personal pursuit of happiness and the good of the community,  Smith wrote that economically at least, if one pursued his private interest (pursued personal wealth) and not his community's interest or his neighbor's interest, the result would be the increased wealth of the whole society.  [productivity, division of labor]  Increased wealth would solve the eternal problem of poverty and the division between rich and poor, slaveowner and slave.    .
