What a parasite family!

I just watched the first episode after watching the second and realized what a parasite bade bhayya's family is. I know there are problems in every joint-family but this bunch is too selfish, mean and self-centered. Why is he taking the burden of the entire khandaan on his shoulders? They have the fathers to look after their respective families. They can earn and look after them whilst contributing towards the whole family. Why does this guy has to take on the mantle? Nimbu ko Nichols rahe hai..poor khoon choos rahe hain...the Chachas very conveniently putting all the burden of money, work and responsibility on the poor guy and then call him laparwah..
