Tom Stiles argues that it threatens our democracy. As Acton said, power tends to corrupt, and absolute power corrupts absolutely. I am more deeply concerned about the corrupting effect of power in the hands of large, multinational corporations than I am with the idea of too much government. Corporations potentially can buy and control government. It seems to me that they, and not government, are the Leviathans of our time.
Do conservatives see the problem? Do they think it isn't a problem? Why not?
When a company gets sufficiently big, the usual market pressures that might keep it from doing evil seem to me to become reduced.
