First: Your English is perfectly fine. As someone that speaks English as a first language; I greatly respect and appreciate you even trying. That's an admirable trait, friend; don't ever feel bad, or especially let someone else make you feel bad for trying to communicate. It's the most human thing there is.

Second: That's kind of my perspective. Ideas are cheap and easy. Idealism paints the perfect outcome, without the really hard parts of making it happen, or the incredibly complicated network of systems that would be effected by trying to reach the target. These are huge problems; entrenchment is incentivized and reinforced on many levels. We often don't solve problems, we treat symptoms, because it's easier than doing what needs to be done to solve the problems.
