Please check your facts , These 4 states are reaping fruits of efforts of other states because center disproportionately invested in these states in last 50 years.
1. Half of India's direct tax collection is done from Mumbai.
2. highest tax and highest industrial concentration is contributed by Gujrat and Maharashtra. 3. Food security is provided by food basket up north and by much maligned states of UP , Bihar and MP. 4. Miniral resources and steel are provided by Chattisgarh , Orrisa , Jharkhand and MP but Royalty per ton given to these states is much less then what less miniral rich states get ( example Karnataka) due to resource equilization policy followed from days of Nehru.
So if rest of India disinvests these 4 states others can grow at much faster rate
