They have the media on their asses to keep them honest and are required full disclosure of almost all public funds(military spending somewhat grey there). But along comes the accountant in a private corporation, sees his opex is cut into heavily by wages.
So they capex some fancy robotic automation overlords to do job x that wage taker did and then 'right-size' a giant chunk of workforce. Suddenly a massive amount of people arent getting taxed, because no laws are in place to tax robots(unless im missing something obvious). The few top end of the corporations are earning more and more so they get to lobby and _donate_ money to government policymakers disturbing basic democracy.
I see the only answer coming from the government increasing a generalist tax(like GST) in order to cover a basic income for the... robotically displaced meatbags... and also to pull into line some feisty corporate meddling.
