So, is the problem capitalism? Is it that big companies are trying to force their way into government so that they can make more money from beneficial legislation? Is it them just being their greedy, capitalist selves?
Well, the answer is yes and no. They are being greedy, but they are also being enabled. Do you know why businesses lobby? Because there's a good chance that they can get legislation passed on their behalf that might make things favorable for them. Now, not all of them do that of course, but if you don't believe there are at least some you must be nuts.
Who is this enabler? The enabler is a government that is willing to legislate on their behalf. In the real free market, businesses wouldn't lobby the government, because they know the government wouldn't respond.
Nowadays, we have people who want to regulate lobbying.
I've touched on this before, so I won't rant, but understand that rampant lobbying is the result of rampant government intervention. If you untie government from the economy, then you can be rid of all those pesky organizations.
