I agree, memes like this act like this isn't a reason to try. It's an illusion to think one solution solves all problems. There are several problems here and having the wealthy pay their share will be part of the solution.
JFC. Yes, both problems exist, and the barrier to taxing the rich are the cunts in control. Cut them out, then the money will go where it needs to and we have greater control over who gets taxed what.
Then why not start with the root of corruption? If the end result is the same, why not go after the politicians that enable the rich to ease taxes to begin with?
Because often times you have to cut a tree down from the top, you can't just uproot it right away. It's the reason we go up stairs one at a time instead of two or three at a time. The end result is the same but we learned as kids it takes a lot more effort taking a few massive steps instead of more smaller ones. Politics takes time, politicians have a lot of voices to sift through. We'll always hear our own voice in a choir, it's a lot harder from the audience.
If you can't change the laws, change the politicians, If you can't change the politicians, change the system. If you can't do either, talk about it until enough people agree and you can. Incremental changes my friend.
"so long as" is the weak point in your approach, IMO. There are separate problems. If you insist on solving them together, probably you fail to do anything. Work on both, but don't insist on a single grand solution.
