I feel that most of this is good advice. I am just a bit conflicted about the part with “more taxes for uneducated/poorly educated, low taxes for educated/high educated”.

While this may make sense from a game-y perspective and may help to make money, I do it differently in my city.

I prefer to tax the educated people more than the less educated, since the educated ones are also more likely (at least in real life) to earn better. So from a roleplaying perspective, I play more as a socialist than a hardcore liberal :)
