Lets say people didn't like the new tax system so much (it made it so hard for the cash to be earned and you had to worry all day long about taxes, just like in real life) and they kinda stopped playing (in the end let's not forget that it's still a game and you need to have fun, not worry about taxes and stuff in the game also)
We currently have taxes but they are lower than before and people are happy now.
Don't get me wrong, its good that you post suggestions, but sometimes not all of them are good for the server.
This is my opinion, maybe others think in a different way.
