Question

What's the difference between "mean to do" and "mean doing"?
I mean to go, but my father would not allow me to. 
To raise wage means increasing purchasing powerWhat's mean by"I don't mean there to be any unpleasantness"?

Answer

"increasing purchasing power" is an object clause. So there is no real verb structure here. All you have is: subject + means + object
In #1 "mean to" means "intend to".

Answer
