I read your paragraph about the history of Belgium and immediately lost interest to continue reading. It's so full of mistakes, you'd be ashamed.
Belgium has it's origines in Revolution, twice: once in 1789 and in 1830. Both times the Belgian people rebelled and chased the oppressors, both times there had been on the day Belgium came into existence a general feeling of Belgian nationality (Belgium had three chances to become a 'nation') and there weren't 'two distinct people'. There were Flemish, Brabantines, Namurois, Liegeois, Luxembourgians, Limburgians... They all were connected by the same culture, but they didn't have one language, they had four languages, some spoke Flemish, some Walloon a minority spoke German and the upper class ALL over Belgium spoke French. The many of the officers in the army were Flemish, but they spoke French. The upperclass called itself Belgian and spoke French and therefore people tend to think they were Walloon, which wasn't always the case.
Wallonia has been less in French hands then Flanders. Wallonia has no French origines, they are Franks, that Germanic tribe the Flemish also descend from, they were proud because of their industry.
Their welfare system is so expensive because there are so many people who benefit from it, for the individual there is no difference because it's a federal thing, it's the same in Flanders.

You keep your silence about a few things.
An independent Flanders has no future:
1) Guess what: the Flemish capital is Brussels. After a long and difficult divorce (the Walloons aren't stupid they will save as much as they can) the EU will do the most logical thing: looking at numbers. Every Flemish municipality with a majority of Francophones will either join an independent Brussles or Wallonia. This means that the Flemish government will be paralyzed for years as the Wallonians will pressure them to leave asap. By the time the Flemings have found a suitable city and build the things needed for it to become a capital, which will cost billions Flanders will have lost many political and economical opportunity.
Hey look at this: the money the Flemish complain about that go to the poor regions of Wallonia, comes back. Many small Flemish businesses exists because of Wallonia: it's a place where they can send their goods without having to know another lawbook.
