There is something that can be seen throughout history of mankind: Some dude leads a country for many years in prosperity and abundance. Because he has results, his opposition is practically non-existent and he stays in the lead until he dies. Another king comes but he is practically unable to raise to the same level as his predecessor. His opposition is stronger (relative to him) and he ends up either overthrown or burning all the money or both... This backlash effect is very clear after almost any powerful figure. Without peers of the same calibre, good results will soon be cancelled out as if non-existent.
