Okay, I can get behind that. I feel a certain amount of government is necessary to stop big business, big gangs (mafia & the like), or whatever from getting out of hand -- but too much government has its own problems. As you say, corruption, whoever gets too big. Similarly, a certain amount of unionisation helps keep big business under control, but too much leads to the workers holding the populace hostage. And so on -- balance in all things, really. Although what constitutes "balance" will vary considerably depending on what you're looking at. (Law enforcement needs more regulation than most industries, for instance.)
