ابن خلدون said this quote

“ The fifth stage is one of waste and squandering. In this stage, the ruler wastes on pleasures and amusements the treasures accumulated by his ancestors, through excessive generosity to his inner circle. Also, he acquires bad low-class followers to whom he entrusts the most important matters of state, which they are not qualified to handle by themselves, not knowing which of them they should tackle and which they should leave alone. The ruler seeks to destroy the great clients of his people and followers of his predecessors. (...)Thus, he ruins the foundations his ancestors had laid and tears down what they had built up. In this stage, the dynasty is seized by senility and the chronic disease from which it can hardly ever rid itself, for which it can find no cure, and eventually it is destroyed. ”
