Then use shorter sentences, Stephen.
Let me tell you a story:
Year zero was a top-down scare story released to the media as a terrifying legend to frighten the lower classes. Those who enjoyed the top steps of the great human pyramid remained in a stable situation. The slopes below were constantly eroded by those scrabbling for height. Trickle-down had no meaning below the top few steps where everything of value remained safely lodged. The precipitous sides of the pyramid meant that anything which actually fell from above was completely ruined on the way down. Criminals attempted the impossible slope using perilous and risky ladders but fell back further each time as they became exhausted. The sides of the pyramid were in constant flow as all the lower classes struggled to maintain their position or gain that above. Their whole lives were spent clinging onto the perilous slope constantly terrified of falling.
Those enjoying the higher echelons remained isolated. They were oblivious to the suffering of those below on the hot and dusty, gravel-laden slopes. It was so long since those above saw anyone from a lower position that they had dehumanised them into legendary beasts. Those below could not see the incredible wealth of those safely ensconced in the clear-cut, gold-leafed steps at the very top. The view was fabulous from the top but everything remained at a distance. Flood and storm were the lot of those far below. Those above were well above such discomforts. Safe in their wonderful caves hewn from the solid rock and decorated with the finest jewels and antiquities. Their fabulous luxuries were passed upwards by safe passages within the pyramid by loyal slaves. Out of sight of those struggling for their very survival on the slippery slopes outside.
Millenia passed and the wealthy whites at the top remained totally unaware that Africa and Asia had populated the lower slopes in their billions. They were all attracted like flies to the stupendous pyramid inhabited by their fellow man. Eventually the sheer numbers crowded around the base forced them to stand on each others shoulders to find enough space for a first foothold upwards. The vast slope of the pyramid was eventually completely covered in human beings. It took a very long time and many were lost in the struggle for height or crushed by the weight of numbers they supported. The vast mounds of the dead became a foundation for upward mobility.
When the overflowing hordes climbing endlessly over their fellow men finally reached the top of the pyramid they found a group of withered geriatrics. Wasted by the UV of such altitude they were blind and riddled with untreatable cancers. However, so many eventually reached the top that there was no room for them all. They began to fall in increasing numbers. Those below, seeing the terrible waste of life, lost interest in allowing others to climb over them. They started to climb back down and walk away from the vast pyramid which had dominated the earth for so many thousands of years. Those who remained at the top fought to the death over diminishing resources because they had no knowledge of the secret inner passages. Without those below to support them there was no way down. So it came to pass that the pyramid was completely abandoned and at long last every human being learnt how to walk upright on the earth. Sleep well!
