It is still a few years behind, though, they did not do very well in the clasifications for the world cup and they were competing in Asia, a continent which in general does not have very good futbol. They would be oblitersted against Argentina or Brazil, lol. Still I am sure in 5 years or so they will improve a lot.
Yes and no, according to Marxist theory, socialism or the dictstorship of the proletariat is the previous step where you build and improve your means of production, develop a counter superstructure to the previous capitalist one and fix certain issues regarding social inequalities, before reaching what is known as a classless society, or also called communism, anarchism or anarchocommunism. Anarchism does not agree on this, though, since authority for it is inherently wrong and malign, therefore it calls for a direct transition between capitalism and classless society.
Regarding social democracy, you should be opposed because it is not socialism in any way, social democracy means liberalism which means capitalism, and the bourgeoisie will never achieve anything more than the bare survival of the proletariat.
Also, you may be confusing social democracy witj democratic socialism maybe? They have similar names but different praxis.
Really good mate.
