Why was Non cooperation launched? How the notion of Swaraj was perceived by various strata in the society?

The role of the non cooperation movement.
Non cooperation movement was Introduced by Mahatma Gandhi during the year 1921 as Gandhi was of the view that Britishers survived in India because of the corporation that Indians were giving them and withdrawing this corporation would let the Britishers know about the anger that Indians had for them because of the condemning act of massacre that Britishers did at Jallianwala Bagh. The different Strata in the society seriously followed this movement:

The middle class people who were buying the clothes manufactured by Britishers, boycotted these materials and Khadi products were being used.
Also the middle class people discarded all products manufactured by Britishers by rejecting to buy them.
the upper class people started rejecting the invitations that they received from the Britishers to their parties.
the lower class people who worked for the Britishers refused to do any work for them.
All the classes of people were showing protests by denying any service to Britishers.
