Well the education level will definetly go on a toss. Think of SENSEX... day this quota shit is implemented i can bet SENSEX will loose 2000 points as FIIs will pull out. And following it will be other financial orgs. so you can imagine SENSEX in between 3000 to 4500 within 2 months of Quota implementation.
This all will lead to an all time market slump as with 50% talent in the institutions like IIT and IIM will mean less investment of MNCs in India. Well then that suggests no job and in the remaining 50% goes to Quota people... and lot of youth will come down to street to Kill, loot, kidnap, etc for food.
