100% reservation is a must from the standpoint of social justice and principles of Mother Nature. If a mother has ten children and if a few of them are poor and the remaining are rich she will not at all feel happy over rich children but will feel totally dejected over poor ones. This is law of Mother Nature. Another law of nature is that cutting across all religious, social etc. divisions 70% of the population are shirkers and only 30% are workers. This is because 80% of air is inactive nitorgen and only 19% is active Oxygen, the proportion having been fixed after very careful thought by Nature to ensure that the earth is not rendered clean-shaven and ecology upset within a very short time. Allowing 30% workers to gain upper-hand is, therefore, not acceptable to Mother Nature, both from the point of view of clean-shaving but alaso from the point of view of humanism, self-respect and exploitation of majority etc. It has also to be understood that thermodynamic laws ensure that every work result in around 70% loss and entropy and consequently there is no chance of any post, whether white collar or labour-intensive, being good or lucrative. So all posts are exploitative only in proportion to their lucrativeness. Thus scientific laws ensure that the more one is meritorious, the more one is exploitative and that is why merit has not been able to gain acceptance or even accommodation by humanists. The advocates of meritocracy should clearly appreciate this great drawback
