If there is no bubble bursting in 1720, we could expect a Royal Bank working. The public debt could fin easier and less costly financing (the french public debt was not that huge compared to the British one, but its cost was far heavier). Fiscal inequalities would continue though, so it is not a magic trick allowing the Royal State to solve all its cash issues. The India Company would have a good influx of cash for the colonial enterprises. Even if Louisana itself is not so boosted, India proper could very well be the price.
