There is some truth in that. It is a fact that in a free society there will be freedom of association. This means that there will always be a chance that governments are being influenced. It is not an entirely bad thing.
Many groups try to influence government actions; giant oil corporations, environmental organisations, banks, trade unions, business interests and so on. How we think of such interests depends on whether we oppose or support their ideas. I don't see how that could - or should - be stopped. I think lobbying should always be open and honest. Public debate will always trump secret decisions taken on the back stairs away from scrutiny.
It is, I think, a necessary part of democracy that people and groups have access to government. A good government (and this is what all here want, I think) will listen to lobby groups - then, having heard all sides, do what it decides is best.
The trick here is to find the best people to govern for us. That, for me, is what the thread is for.
