Sword in the Stone

You place your hands upon the hills of the sword stuck in the stone Hoping you might be the one chosen for the throne But as you start to struggle and the sword, it doesn't move You realize you're not worthy, you had so much to prove As a scientist, he'd often been to Greece He knew that clamp and lever would control the sword's release Don't ever think the powerful would leave power to chance Everything is carefully arranged well in advance And just as with the sword and stone you used so long ago The powerful still pull the strings as small folk come and go The winner of the football game, the duxes of the school Your friend got that promotion, not chance, don't be a fool The world, it isn't merit-based, no one keeps fair score The strong, they scheme and stack the deck, they're always craving more But what is the desire of the shadowy strong hands That multiply like cancer spread across the lands?
