Earlier quoted context omitted.
I should have been more clear with "more say than the rest". I referred to making the laws of the country. In Finland the parliament makes the laws according to the constitution and everyone has a single vote for electing members of said parliament. From what I know companies have no extra votes to give for representatives.
Do they have extra money to give to representatives?
more recently there's the novel shortcut of the business people themselves just running for office. Our current PM has a long list of business interests, including lobbying the Modi government on behalf of a startup he co-owns to sell them a chemical plant. His family also has holdings in a mining company that has received considerable amounts of government money, a fact he actually tried to cover up with in the Finnish state media Yle.
So painting this as "why is it business' fault what government does!" is more than a little misleading. Government doing exactly what business wants is the whole problem.
