Close. Government can be a force for good, or not, depending on who's in charge. If you have bad leaders the government will be bad as a result. If you have a good government, it will be a force for good.
A lot of liberals distrust human desire if you mean desire for material things. Many would say that the accumulation of stuff for the sake of accumulating stuff is unhealthy, and that if you're rich, you have an obligation to give something back.
That is where the nanny state/redistribution of wealth idea comes from. You don't approve of the accumulation of "stuff" so you decide it is in our best interest to take that stuff away from us.
I'm okay with you giving your "stuff" to others. Heck, I used to give some of my stuff to others. I am not okay with you deciding that I have too much stuff and therefore I have to give my stuff to others. That simply is not your decision to make.
Note: in that example "you" and "I" are not to be seen as literally meaning you and I but rather liberals and society.
