These include support for a "universalist" welfare state aimed specifically at enhancing individual autonomy and promoting social mobility; a corporatist system involving a tripartite arrangement where representatives of labor and employers negotiate wages and labor market policy mediated by the government;and a commitment to widespread private ownership, free markets and free trade.
