I would argue that the main reason isn't FOMO. It's increased awareness, resources to educate yourself, and resources to participate. All of these come from the Internet.
Awareness definitely shouldn't produce more active traders, since casual daytrading is almost always suboptimal compared to other casual investing strategies, even before you take time overhead into consideration. I'm sure this has more to do with platform access and the ability to skirt day trading rules by having nearly infinite free accounts.
