This is subjective IMO. In a global world, most children not necessarily stay in the same city or even country as their parents so yeah maybe they have reunion 1-2 times a year, for the rest you are on your own. 

My view is, if you want to have kids, go for it, but please do **NOT** have kids for the sole purpose of not being alone when you are old!

Yes! It is not your children's responsibility to take care of you and meet your needs.
