The road is beyond rocky.
Every political force will tell you, for example, that the State should support small and medium companies. They probably have in mind lots of subsidies and State-funded internships that will only serve to fund unscrupulous businessmen at the expenses of tax-payers and the interns themselves. They can hardly think that all the licenses, declarations, forms, tax-returns, etc., all those annoying and often imbecile procedures hurt a lot more the small companies than the big ones. And they can hardly think, or if they do think, they do not act on it, that complex fiscal systems only defend the richer, the best informed, those who can pay for someone to play with the law or win the subsidies. No political force realizes that the more power the State (and the local authorities) has on the economy, the bigger problems such as corruption will be. Centralization is not only economically hurtful. It is morally wrong and ethically deviant.
In our near future, we may get to a situation in which the Welfare State starts being dismantled because we need to cut costs. But the problem in Portugal is certainly not a big Welfare State. Checking OECD data, you may easily find out that Portuguese Welfare State is as big as any other European Welfare State, certainly smaller than not few of them. And that non-biased analysis of the Welfare State is what distinguishes a Left Liberal from many other Liberals.
What we must question is where all the rest of the money goes in Portugal. Why do we have so many doctors (and we do)? Why do we have so many judges (and we do, despite our calamitous judicial system)? Why do we have so many unproductive public investments? Why so many subsidies? Why so many taxes imposed for "social justice", with no positive effects whatsoever after all the tax benefits that only benefit the rich? And it is this critical view of the State's power of intervention in the economy that distinguishes a Left Liberal from the Socialist Left.
The road is rocky - but I still believe that a Liberal Left, a Liberalism that knows that (sane) social policies are crucial for people to be free, a Leftism that understands that economic growth is crucial for social justice, is the only key for our future. We need to continue of road from religious serfdom to rational freedom. We need a State that keeps its hands off the economy. We need a State that guarantees that everybody has some chances in life. All of these three goals are only possible through the combination of a Leftist inclination and a Liberal reasoning.
