Why do escalator handrails never run at the same speed as the escalator itself does?

Question

I assume some of you observed this before. When using an escalator I mostly notice that the handrails run just slightly faster/slower than the escalator itself. This is especially noticable when leaning against the handrail at the beginning; when at the finish you’ll most likely be tilted either up- or downwards.
I noticed this at multiple escalators around the world. It seems like this is a worldwide problem.
Can someone explain this difference in speed between the escalator and the handrail?

I ride on an escalator every day and the handrail moves at the same speed as everything else.
