It is less corrupted. Without capitalism personal connections is the only source of power, so the only ones with power would be politicians and their friends. With capitalism we create another bastion of power, the capital class. Communists are politicians who don't want to share power with the capital class and instead hog it all for themselves. We all know what happens when politicians has no group to oppose them, everything goes to shit.

Maybe you could think of some other system where personal connections isn't the only source of power, but so far democratic capitalism is the only thing we have.

Edit: As for your scenario with capital paying money to influence politicians. The alternative is that the politician already have all the power (and money), nobody has to pay them. To me it is better that there is some corruption with money going to politicians rather than politicians just having all the money from the start.

> Corporations literally buy laws via lobbyists.

Both elected and unelected officials are so corrupted that they take money from the corporations to choke the competition on the free market. To fix this issue, let's give them even more power. That will show them and they'll stop being corrupted.

Why not outlaw professional lobbyists and private funding of politicians' campaigns? Once all bribery is illegal it could be easier to enforce consistently.

Can you name a country where lobbying is illegal? It's a core function of democracy.

> It's a core function of democracy.

Lobbying is not democratic. Corporations have far more money than individuals and therefore far bigger lobbying power. As a result, laws and policies will reflect what the small elite wants rather than what the people want or need.

Because of lobbying, the copyright monopolists have systematically robbed of our public domain rights. Because of lobbying, we might as well not have the right to reverse engineer anything.

Lobbying is literally billion dollar industries asking the government to help protect their interests. Hard to think of anything less democratic than that.
