WEll said delusionsofNORMALity.
However I think that the higher man can definitely manipulate the lower man without becoming lower. Like Peruvian Devil said, you can manipulate the lower man to a more high point of view, because they are not capable of becoming higher by themselves. By this I mean they are not really able to exercise free-thought and look into things themselves without being biased towards the popular or common view.

I think higher people are the same as lower but the only difference is that they CAN think freely and do what they think is right. But that makes a HUGE difference.

Whether it's better or not is up to debate. Higher people have solace in the fact that they are more intelligent or free thinking than lower people who just blindly follow. However it is a lot easier to just blindly follow and you will probably be happier doing so if you've never known the state of being higher. Ignorance is bliss so they say, I tend to agree but....

Alan Watts, who is learning Buddhist Zen, has spoken on the topic of so called higher people. But he says that when you reach enlightenment you will realise that there really is no higher or lower type of person. This is because there really is no correct way. Why is being a 'higher man' better than being lower?

So when you are enlightened you are probably the 'highest' you can get. But you realise that there is no higher or lower. Therefore you can go on being happy as well just like the 'lower' people.

It's hard to explain, especially in a forum but if anyone knows what I'm talking about please explain it better than me lol.
