The French riots are not a problem the French state can solve at this point. And Hegel knew why: Indignation.
He spoke of a rabble that's produced by the modern capitalist state. Just as unimaginable wealth is created by markets and capital, there will likewise be those who are left behind and can't be integrated. They're not simply poor. The rabble's problem is that it cannot sustain its own life through its own work, yet doing exactly that grants a person dignity, self confidence and pride of their own work.
Welfare, sustaining people without their own input, cannot fix the problem of dignity. The rabble has nothing useful to offer to society. They experience it not as a system that can serve its own interests but as a system that functions and reproduces itself without them, wealth they have no part in. So they destroy it. They burn cars. They burn schools. Destroy infrastructure. It's not their state, it's the enemy's, so it's fine.
These people grow up in a society that promises them self actualisation, a decent job, a certain amount of prosperity, yet have no means to realise that. On top of that, we see the indignation take a racial dimension: In their view, the reason they become the rabble is not their inadequacy to the demands of the job market, or the decline of Europe's economy in general, no, the state is racist! And any exclusion is interpreted as racism. The Whites are the enemy.
The symbols of the White French state become unacceptable, as they're the symbols of the Enemy; Palestinian, Moroccan and Algerian flags are chosen, not because they actually feel connected to these Muslim nations, but they're the Friend the Enemy produces by the dialectical movement — you need allies to fight the hated state that will not give you what you want.
The state cannot simply solve the indignation these people feel, out of the massive gap between expectations and reality. Hegel knew it. The state cannot solve indignation on its own. He recommended expanding into other markets, to create an abundance of jobs, or sending the rabble away, into colonies, where they can build a life of their own. That last one is the hint on what we should consider.
