Employees of corporations donating to campaigns when the dissolution of that company's business model would affect their employment is pretty much the highest degree of alignment you're going to see between corporations and their employees.

And corporations can't donate to "campaigns" but they can perfectly well donate to PACs aligned with campaigns.

> And the politicians aren't actually "bought" by it. It's more like they already agreed, and maybe they're being paid to stay politicians instead of getting a better paying less annoying private sector job.

But nobody said they were bought. It's not corruption if it's legal, right?

The problem is the systemic bias it introduces. Politicians need to raise money to stay in office, so they have to appease whoever has money. So politicians who appease special interests have an electoral advantage, win more elections and constitute a majority of the legislature.
