what you think..is today there is need to avoid joint family??

wooo joint family!! doesn it happen nowadays??? i think most people prefer staying alone. like 2 in one family!! it was in earlier days where people believed in joint families! they believed that people in joint families would care for each other!!solve other peoples problems! consider others problem as their problem... and so on!! but nowadays.. this thought has been changed! people think."we are not able to sole our own problem, how could we consider others problem as our own problem and solve it"?? this is todays world! so i dont think there are many families who prefer joint family!
