A pyramid was a symbol of power during a pharaohs life?

A pyramid wasn't so much a symbol of power, or else all high class people of the time would have had one. Instead it was made for two reasons: 1) It was a place where a pharaoh could be buried with all of his possession and those who were to follow him into his after life, to serve him, could be buried. 2) It was a 'landmark' of the pharaoh and his rule, each pharaoh wanted to be remembered, and to be remembered as the strongest one ever to rule, and this is why pyramids very in style and size.

It has been speculated, but not proven, that pharaohs also used the pyramids in order to keep his 'subjects' to busy and tired from revolting against him/her. Also that the idea of working on a pyramid was a threat to anyone who messed up and pissed off the pharaoh. But like stated above; this is a speculation.
