From a Dutch speaker's perspective, may I say your view is quite biased here?
My view is quite biased on on there history here:
The Belgian revolution of 1830 was the work of French republican and napoleonist exiles living in Brussels, and rebels from Liege. Together they succeeded in driving the Dutch army from Wallonia and subjugating Flanders by force. Though the revolutionaries wanted the annexation of Belgium by France, this was vetoed by Britain and the country became an independent state run by an establishment of French immigrants and Liegeois.
They eradicated the decentralised Netherlandish political traditions of the country and ran Belgium as a centralised copy of France. If Belgium had been established as a second Netherlandish state, it could probably have become a viable entity. As it was, however, the project to turn it into a second France was doomed from the beginning.
Although the majority of its people speak Dutch, Belgium has throughout its history been dominated by a French-speaking establishment. Throughout its entire history Brussels was a Dutch-speaking town, until the middle of the last century, when the deliberate “frenchification” policy of the Belgian authorities succeeded in turning it into a predominantly French-speaking city. When in the early 20th century the country gradually began to democratise, this establishment feared that the Flemings would become the rulers of the state. Hence, Belgium was federalised giving Wallonia a constitutionally guaranteed veto over all major decisions and a guaranteed share of half the seats in government and major administrations. The conservative, free-market oriented Flemings have been complaining for decades that they are forced to subsidize tens of billions every year to the Socialist south, while no improvement of the economic situation of the Walloons has been visible. On the contrary, Wallonia has become one of the most corrupt regions in Europe with hardly any economic growth.
Though Wallonia has 33% of Belgium’s population, it has 46% of its unemployed and it accounts for only 24% of Belgian GDP and 13% of its exports. 20% of the Walloons are unemployed and 40% work for the government. The only regions of Wallonia where there is an entrepreneurial spirit are the regions bordering Flanders just south of Brussels, the provinces of Namur and Luxemburg and the German municipalities (GM).
