Most revolutionary thinkers don't think replacing the existing leaders will "magically" lead to a better society.
They have grievances with the existing systems, reason to believe those in power won't address those grievances, and reason to believe replacing those in power with people more sympathetic to their grievances will address them.
Also, there has been a boatload of revolutionary thought about how to make a better society over the last century or so. There are clear ways that our system is imperfect and clear ideas of how it could be improved. I'm not sure why you claim there are no "intellectual improvements" over the status quo.

So they are doing exactly the same as those in power, which is taking care of themselves.
