It's coming. Inbev (#1 brewer worldwide) wants to buy SABMiller ( #2 brewer worldwide) for $104 billion. Combine the #1 and #2 brewers and you have a world wide monopoly. They will be able to hike their prices without fear of competition, there is no competition.
The anti-trust division at Justice ought to fight this merger. If anti trust means anything, it means the two top firms in any one market cannot merge. The two top firms are supposed to compete, on price and on quality. The merger just eliminates competition, so they can hike the price and lower the quality and get away with it.
