I think a good first step would be an Aus style bill that breaks down how your tax dollars got spent by the share of the budget that went to whatever we spent money on.

Actually seeing how much money went to foreign aid or debt repayments or MIC contracts would at least start an informed discourse on how are taxes get spent

Won't happen unless immediate and immense pressure is applied to politicians. Such as threatening their livelihood by not paying taxes (their paycheck)

Or you know, violence. It's easy to beg for change, but without action they are under no obligation to do anything.
