Not really.

Years of broken promises, raised taxes, decreasing working conditions, etc...

The taxes Macron tried to pass recently are just the last that broke the camel's back

Furthermore they more mostly affecting and impacting the middle and lower classes.

France is one of the most, if not the most, taxed country in the world and people end up having to give away more than half of their monthly salary. People can't save anything and many end up in the red way before the month's end.
Upper classes on the other hand can benefit from tax exemptions and also earn enough to either save and/or place their assets abroad in the so called "fiscal paradises".

The YJ movement is not about "free stuff" or "self determination".

You can't keep adding taxes upon taxes without raising the minimum wage.

General protest are either organized or backed by political figures, partys or unions.
This is not the case with the Gilets Jaunes.

And the Gilet Jaune movement has nothing to do, and cannot be compared, with previous movements.

Sure, recently other movements joined in. But the YJ movement is mostly unaffiliated.

@Euro looking for a green card Well, sorry for giving a French perspective to a French movement. 😄

There cannot be a list of demands, simply because there are not leaders.
Several lists have been made, but none are legally recognizable.

Hum nope.

Because though united, the YJ is not structured. There are no leaders, there is approved chartes, or list of demands.

Here is another "list of demands":

it is not legally recognizable either.

Just a list of demands.

But it does not represent anybody in the sense that nobody has been consulted to make it. There hasn't been any debate, discussion, referendum or anything.
For all we know it could very well be a group of 10 dudes who made it over the course of two or three days.
