Most people aren't aware of any particular industry or business that causes difficulty for a minority or permanent damage to the environment somewhere most don't see or some critical infrastructure most people aren't aware of unless some media choose to point it out. There's no way to be aware of every scam that some faction with a bunch of lobbyists and business connections to media outlets is running - they thrive on silence and/or misdirection and the effort to keep it is a predictable business expense and an industry in itself.

edit: If our government, in order to act, has to rely on the majority of the population both understanding every critical subject and forming a similar opinion on those subjects that is in opposition to current policy, then our government has become purely parasitic.

Honestly, it's called policing, and it doesn't just have to happen to poor people.
