People have been trying that, for at least a few decades.

Do facts like almost every American wants a more fair system change it? No, because the governing structure has itself been corrupted after decades of abuse.

Therefore, it seems the most effective means of causing change -- given that what you suggest has failed for decades -- would be to cause direct financial harm to those who are actively corrupting the system for their benefit, as that changes the calculus for them and incentivizes stopping.

This is a downright civil way to do that when society breaks down -- the poor used to just stab people over bad tax law.
