"On one condition: that a significant rise in the price of a barrel does not generate faster than expected this situation of high cost and shortage sought by overtaxation. Because in this case, overtaxation becomes unnecessary."
that's for sure the tax would cushion the shock so it will have to be adapted according to the price of orgine otherwise it is stupid. But we must not forget that due to speculation, the oil could fall temporarily so someone who invested a lot to consume less would risk having problems then he could appreciate like the others besides a lower tax / VAT or whatever, fueled by the profits from the oil tax, which would be high if oil was not expensive.
* "So if it is true that even without a surcharge we risk such a recession, sooner or later, I do not see States advocating decrease, which inevitably must lead to reductions in tax revenues, job losses, companies that lose markets, ...... etc, in short a total overhaul of our societies, therefore political instability and therefore an embarrassing situation for our leaders ".
If the increase in the price of oil brings recession it is largely because our money (our work) goes abroad to pay for this oil. With a tax, part of the money (our work) goes back to the state (nothing is lost) and it can (and must and this is where we have to be careful, this is the danger) redistribute it in the form of lightening of charges (employment aid), increase in wages (increase in consumption not related to energy it can be services, art / entertainment or research or other non-polluting activities) , or invest for us in systems that do not require petroleum (eg solar heating) and in these cases, we are effectively preparing for expensive petroleum since we are becoming less and less dependent on it.
