You sum this up yourself in one quote
Life is gonna be a grind for you lot and this pleases me.
Why would it please you that some wankers on the internet who you've never met and probably never will would have their lives be a grind? It's warped.
People are happier when they work for something and achieve things through their own hard work rather than having everything in their lives handed to them by their parents. It gives life meaning if your success make your life materially better and your failures make it worse, if you know that whatever happens Daddy will look after you, who cares?
Maybe that's just a lie that people who work hard tell ourselves, but your actions and attitude on here don't seem to be those of a very happy person.
