Who passes those laws? The politicians bought and paid for by the same companies?

That's the failure of the people. Those politicians are supposed to represent their constituents - not their highest bidder. Democracy is not a system where people choose a politician and hand them the power and authority over themselves for the next half a decade. Instead, people have to constantly and consistently boss them and hold them accountable. This is the duty of every citizen towards a democratic constitution, without which the latter is not even viable.

I know what response to expect for the above. It will be contemptuously dismissed with the remark that it's just a fantasy. But I hope you're seeing the congress people running out of town halls via the backdoors in disgrace after their constituents heckled them and challenged their demagoguery. Sadly, it's a tad bit late. This should have been the response to much less provocation. Still, many of those politicians are now afraid to blindly endorse the ideas of their overlords. This concept isn't new either. This was widely experimented with during the French revolution. They had provisions to recall and replace the reps in such instances. What people need are political education and a strong allegiance to the constitution.
