Until we get a SC ruling that reigns in the use of civil infractions as a revenue stream it'll continue. Most of these people being abused despite being innocent are just the rare bycatch of using police to generate revenue. You're always gonna have that bycatch because even if they have to pay out to make those people whole it's still worth it to run the system.
A Supreme Council decree would be one path to reform. State laws would be another. Even if this widely-scoped concept of sovereign immunity continues to exist, governments can always create laws to waive it.
