Equality is at the core of a 1 person, 1 vote democracy. Your vote is a unit of direct political power. It doesn’t matter who or what you are, your vote matters just as much as the next person’s. It doesn’t matter what title comes before your name, or what your bank account statement says, at the end of the day my vote is just as powerful as yours. Without this equality democracy couldn’t function.
Unfortunately, things are not as simple in reality as 1 person, 1 vote. Is money speech? Is it a form of your free speech to choose to give your money to a political cause? If money is speech, does that mean those with more money have more speech then those with less money? What if a small group of people pool their resources so that they have an inordinate amount of speech compared to everyone else? What if they use this inordinate amount of speech to affect politics? Now you no longer have 1 person, 1 vote system. Money = speech = power; money = power.
At this point democracy starts to crumble. A person’s vote becomes irrelevant when there are much larger units of power in play. It’s similar to the difference between an arithmetical increase and an exponential increase. A large group of individuals can coalesce around a cause, but if another group has more money, they will have more influence and power. Congratulations, you’re now on your way from democracy to oligarchy.
The degree to which you’re an oligarchy depends on how much big money is involved in politics. This issue has always been around since the start of democracy, however, only relatively recently have we’ve seen the advent of super PACs and corporations pouring millions into politics in order to twist the law in their favor. The more money in politics, the less democratic those politics become.
“Well what’s the problem with that?” some might ask. If you’re fine with some people having more power than others, then you need stop your flag waving and acknowledge that you don’t support democracy. While you’re at it, stop using democracy as a buzzword completely. Democracy as a term has become as debased and valueless as liberty, freedom, and terrorism have in the past decade. They are cheap, gilded terms devoid of any real meaning.
“Why shouldn’t the rich have more power? They have more stuff and thus more of a stake in society.”
No. The amount of material objects you possess doesn’t matter. We all have the ultimate stake in society, our lives. When someone dies for their country, we say they paid the ultimate price. It is the most valuable thing we have as individuals. Your fancy cars, houses, and trust funds are drops in the bucket by comparison.
