You vote against your own self-proclaimed interests.
You can’t vote conservative in the 21st century without being either a self-interested jackass trying to protect your own hoard of wealth, or an idiot who has been convinced by the wealth hoarders that conservatives are looking out for anyone but them.
The people you vote for are the reason why this planet is on a collision course with fucked. The only reason Elon started bought an electric car company is because he saw a market ripe for exploitation and convinced idiots that he was a Stable Genius who wanted to save the world so they’d buy his shittily-made cars. He’s the richest person on the planet and could easily solve untold numbers of problems threatening humanity and Earth by himself, but he’ll only do the things that will make him even more money in the process.
