No they just need killer robots to shoot anyone who gets uppity.
Are you talking about violent revolution?
Some disorganized thoughts:
1. The professional classes are so unused to violence, they'll probably undermine the chances of violent revolution (e.g. reflexively supporting gun control, seeing such voilence through the lens "school shootings" and other crime, and being likely to report it, etc.).
2. The professional class is losing a lot of its economic power. The time for solidarity and non-violent action way 5 years ago, but the "happy to play along" professionals (e.g. libertarian software engineers) botched their best opportunities. From here on out it will be harder.
3. As all of this is happening, technology is helping to undermining the ability of the masses to do anything about it: IRL community declining, people getting mesmerized and isolated by social media, AI-enabled surveillance, AI-enabled astroturfing and propaganda, autonomous AI weapons, etc.
4. Even if what you say is true, the clock is ticking. Wait a generation and the "former professional class" will be gone as a distinct thing, and their kids will join an undifferentiated mass of poor who have normalized and internalized their circumstances, as they have no first-hand experience of better times.
