"Or we could tax the rich and give that to the poor!"
Think about that for a moment. Rich people typically have a lot of power, and adding taxes onto them will make them very angry. So you're basically taxing the people who let you use the internet, the people who make your electric cars, and the people who you basically get all of your supplies from. Unless you're living off the country, or know how you can live off the country/land, those rich people can literally just stop letting you buy their equipment. Essentially people who probably don't even know how farming or making your own stuff works (I supposed you don't) will be dead as a doornail without their equipment. They can just sell their stuff for people who don't support them getting taxed or the people who don't tax them, as it's perfectly legal in this mixed economy. If you wanna start saying "Socialism is the answer", then you're dead wrong. Socialism will either allow them to abuse the system and basically use people like you as slaves while also owned everything you have, or it will just make them as poor as you so you'll rely on the government for everything you get, thus basically making the government own you, and in that case we'll be a communist country like the Soviet Union before you know it. Of course some people will probably get mad at the rich people for not letting them have stuff, and in that case they'll probably begin protesting, rioting, stealing, etc, thus causing a civil-war leaving countless people dead for something so small.
Yeah, that's what simply taxing the rich will get ya'. It probably wouldn't effect me much since me and my family typically buy local products from stores that aren't owned by "rich people", and we simply know how we can grow crops and such, so people such as I won't be effected as much since we know how to make a living by ourselves. There's also many disadvantages for getting an electric car, and let's not forget it's mostly rich people who make these electric cars and sell them, and in the case they don't stop letting you have these things that'll mean in order for them to make a living they'll jack up the prices on their equipment, thus making those taxes basically a major disadvantage.
All these things could also lead into another great depression for America so that we'll rely on the government, blah blah blah, you get my point.
