Education not a provision for old age

There is a saying that 'Education is the best provision for old age'. This may be true when thought from the point of view of an individual. Education teaches a person to deal with old age.
However, when we look at the saying from the point of view of a parent, I think the saying falls apart. Let me explain:
All parents expect a child to be better than them and be with them in their old age. But this education has prevented the younger generation from letting this happen. In India, most children from all states aspire to be in top institutes in the country and then get excellent jobs. For this purpose, they leave their home and parents and join the prestigious colleges in some other part of the country away from their hometown. Later after taking up jobs in some of the best companies of the country, they start living in a city, away from their home. Children learn to live without parents and later on marry a girl and settle in cities away from their home. Children expect parents to leave their hometown and join them in the cities which isn't acceptable to most. (And thats quite valid. I mean why should they leave a place wherein they are well settled and enter an unknown city). So, most of the bright young students leave away from their parents.
If thats the case, how will a child be a 'parents' budhape ka Sahara'. The parent is left with no choice but to be dependent on their relatives staying nearby or neighbours. The child especially the boy from whom it is expected that he'll take care of his parents lives in a place far away from his parent when the parent most requires him. Especially when it comes to health problems and other things, the child reaches his parents' place at the last moment when almost everything is taken care of by neighbours.
The problem of getting leaves from workplace and other committments make the matter worse and the boy/girl tends to be away from his parents for most of the time.

I believe that this has become a trend in India (In Maharashtra, where I leave, trend is working in Pune, Mumbai or going to the US). While the child benefits from getting better prospects, it is the parents who lose by having to lead a lonely life away from their child.

I am one of such persons who stays away from parents and wish to really go back. However, now I feel that now I am caught up in this viscous cycle - B-School then a job in a city, then marriage and settlement in Mumbai or Pune. I feel I will never be living with them at their place (Sangli).

Thus, it is this education that has rendered me useless when it comes to be a provision for my parents' old age.
