If You Can't Beat Them, Join Them

I had a funny thought yesterday on the way home from work. I was thinking about a quote that went something like "politicians follow the money, not the idea". And I thought no, there is always an idea behind the money. It's just that wealthy groups get their way, get their ideology into law because they have the money. In other words they are represented but the vast majority of Americans are not. I do agree it is unfair that the distribution of representation in government matches the wealth distribution and not the population distribution. So if that is the case, how do you fix it? Why can't Americans form lobby groups based on their ideologies, contribute to them and use them to lobby the same politicians? Imagine a people's lobby group with 50million members lobbying to end oil taxes, or gay marriage, or to support gay marriage. Whatever it is isn't important. We were taught that representation in government is a direct line from citizen<->Congress. But big companies know that isn't true. It is really citizen<->lobbyist<->Congress. So if you can't beat them, why not join them?
