Also, technically, companies also don't really exist. People do. A company, no matter how big should be allowed to fail and die. A human life matters a lot more. Does it? Do we want it to?
Maybe we should start optimising our policies not with respect to GDP or economical growth but with respect to the actual living: humans, animals, fish and even plants.
If we do want companies to vote then let's make it official. But then there are unlimited number of companies we can create.
Let's vote with money than and stop being hypocrites. 1 person with 1M trumps 900k with $1. Whomever has $$$ can vote be it a company, person or dog that inherited the money. At least in this way we know how it works and change our behaviour accordingly but at least let's be honest about it.
