Why assamese people don't do business or manufacturing ?

Why assamese people are not interested in business or manufacturing ? I have seen in guwahati and also in upper assam. Most businesses like furniture, barber shops etc are run by non natives. Most blue collar jobs are done by non natives. Most assamese are only interested in government jobs. And after getting government jobs they will do corruption. I have seen e rickshaws called as "toto's" plying on the road of assam. But all of these are imported from delhi or from some other states. Why is it so ? Why can't assamese people make stuff and sell ? Even clothes tailors also, most are non natives. Why assamese people are not doing cloths business ? Even foods also like biscuits etc mostly are imported from other states. Why can't people make pitha, laru and package and sell them. In villages there are lots of land. Villagers can come together and create a manufacturing co-operative. Villagers can make bamboo products and sell. Now there are e-commerce options so people can sell online also. I feel all of it is due to assamese culture. During axom andolon many assamese students used to sit in streets and do shoe polish to earn money. But after that it's all vanished. Every part of the world you go native people are involved in business. First priority is business and then jobs. Other countries native people aren't afraid to do blue collar jobs. But in assam nobody wants to do. Assamese intellectuals, assamese social activists like samujjal bhattacharya, akhil gogoi etc should speak on this. Why is no assamese doing anything for this. I feel blue collar assamese workers should be feted, given awards. This way assamese youths can be encouraged to be self employed.
