稍有农业常识的人都知道 ,盐碱地上长不出好庄稼 ,如果想多少有点收成 ,也只能种些劣质高梁。所以 ,不采取科学措施改造盐碱地 ,比如灌水压碱什么的 ,那就甭指望过好日子。社会体制似乎类同土壤 ,好地下优种 ,年年丰收 ;孬地下优种 ,逐年退化减产乃至颗粒无收。所以 ,完善社会 Anyone with a little common sense in agriculture knows that good crops can not grow on the saline soil and that if you want a little harvest, you can only plant some inferior sorghum.

Social system seems to be similar to the soil, good underground superior species, annual harvest; 孬 underground superior species, year by year deterioration of yield and even crop failure. So, improve the society
