Why USA returned characters are so stupid

Seriously doubt MD is a renowned classical dancer with a Gurukul in US who was a single woman earning a living most her life

Her mentality & language is of the gali mohalle ki chugalikhors.even the supposedly educated Barkha is just kitty party gossip queen

Anuj and Ankush doesn't look like USA returned business man . Anuj is seriously such a huge businessman who met Barack Obama an downed billion dollar company doesn't act or think like a business tycoon guy 

Not just US, the show has a problem with educated and hardworking people as they are constantly devalued. 

Anpadh Maa has the solution to all the world's problems. She never takes work seriously unless it involves her filthy phemli. Gavar Jhuli is the purveyor of all knowledge despite only spewing verbal diarrhea. Shameless shahs can enjoy a comfortable lifestyle without doing much except manipulation and abuses, as their unpaid maid dug deep and struck gold. While others are dumb fools who keep staring at this spectacle or singing paens in their praise
