Big doubt pls clarify

Not much has been shown about mami's son in the US. If they have a son there and also they planned to settle there them why their financial condition is shown to be in crisis. Why is suman supporting the family.  I understand she has a loan to pay but it almost looked like she is the only bread winner in the family. Ammi missing something here? 

as far i know suman contributes to household expenses  .. her mamaji works and mausi does do some work .. there was a line in some of earlier epi ..

Mami son in US in doesn't mean he is rich person. Maybe he Is doing job there. And you know living in USA how much expensive is that And not only sumo mamaji Also working. Both sumo and mamaji supporting family and nanaji was a big lawyer so maybe he have money in bank too
