This Comcast-Time Warner deal is clearly an agreement in restraint of trade that should be blocked by antitrust laws, but probably will not be. These huge deals creating a few dominant companies in almost all sectors of the economy are bad for America in the long run. Google-Yahoo, JP Morgan-Goldman Sachs, Comcast-DirecTV, GM-Ford, United-Delta Airlines, all of these, and more, oligarchies dominate their markets. They can largely ignore their customers, because their customers have little or no choice. If you want this service, you have to work with two or three companies; that's it.
Obama is a Democratic President who should be concerned about this, but he and his attorney general, Eric Holder, are too concerned about gay marriage and killing American citizens with drones to worry about antitrust issues. We might as well have George W. Bush as President.
