Big Companies & Big Government

[Tony Thompson]

...are like ice cream and cake?

My coworker and I frequently debate the question of:

Is government action necessary to monitor big business, so that the business does not get too powerful and monopolized?

His argument is yes, government needs to intervene; but at the same time not get too involved.

My argument is the reason businesses get too powerful is because of government through lobbying/influence to modify laws that benefit big business.

What do think? Does business need any watch at all from govt? Or is a small amount of watch needed from govt? How involved should the govt be?
