Makes sense this is how capitalism will grow - once you've refined and streamlined things as best as possible and maximized your market, your next way to continue to grow is to buy up more companies (or farmland) or expand their operations into more sectors so line goes up.
Seems like we need to figure out a way to prevent this from becoming a race to the bottom in terms of quality (and a race to the top for company profits), or turning into mega-corpos only.
