Government's sole purpose is to protect big banks and companies and fool the people it's for their own good.
Government is - at best - an emergent agent with a lot of internal incentives to keep itself going. It does what the people in it want to do. It does what legislation tells it to do modulated by the people interpreting and implementing those statues.
Big Banks and certain Companies and industry advocacy groups spend a lot of money on putting people friendly to them into Government, and that introduced a bias in the collective decision-making process. It should be (and will be eventually) counteracted.
Sure, there are different ways to do something about this, the extreme is of course to abolish the Government, but if you were to think a bit about the consequences and requirements of such a change, you'll see that it's not really the best option.
10,000 years and still waiting
We're still not done with this Enlightenment thing.
Big banks and certain industries have outsize influence because we are a capitalist country where peoples' well being depends on having a job, which is created by a company and bankrolled by banks.
That's why industries like the auto industry have so much more political weight than the tech industry, despite the latter being far richer.
