Far more industry leading companies (much less companies as a whole) have rose and fall in power, changed their goals/products/management/etc in the past 5/15/50/etc years than governments. Turnover is far higher in corporation management positions than congresses and parliaments, and further, there is no law saying that I have to buy any specific good from a company, whereas I don't get a choice in which government I pay to build the the roads or police where I have established my life.
