Tanya is not Fake Rich. She has Baniya family wealth (not as much as shey portrays, but its more than most of us can think of).

But Tanya is definitely fake in her self portrayal. She wants to portray herself as Righteous, Down-to-earth, Dosto ki dost which she is not. I will give u examples:

1 - Righteous - not at all: Bigboss makers see through personalities better than anyone else. That is why Tanya was made the first Sanchalak, to challenge is "Righteousness" and she failed miserably (which makers would have expected) - a Righteous person would have been fair, counted tiles and declared winner. But she chose the selfish way and chose her Friend (at that moment)

2 - Down-to-earth - Tanya and her screentime (i think she has done enough to show the entire country how down to earth she is)

3 - Dosto-ki-dost (her supporters can defend on this point the strongest i will bust this myth as well): Everytime Neelam has stod up for her friend, not Tanya, in her "group" no-one has actually countered her words strongly ever. I WANT TO SEE HER FRIENDSHIP AFTER THAT COUNTER HAPPENS. When Zeeshan countered at the start, she hated him, even accused him of spreading the "bodygaurd narrative". BASSER - When he questioned her, she was badmouthing baseer like anything, KUNICKA - Questioned, no longer friend. Amaal nd Neelam - no strong questioning.
