Here are three reasons from the story that might make Kanta feel unequal:
1. She lives in a slum and has an open drain behind her house while her employers Jain Madam and Jain Saheb never have to face such conditions.
2. She cannot take a day off from work when her daughter is sick as she needs money from her employers as advance to take her daughter to the hospital.
3. At the end of the day, she has to again stand in a long line at the government hospital along with many other poor people while her employers never have to face such difficulties in getting medical care for their families.
