I would never consider placing my parents in a HOME. My Grandmother was in a home for Medical reasons and hated every minute of it. As long as I am breathing I will make sure that my parents live their life as they wish. It is a child's responsibility to take care of their parents like the parents took care of them in infancy.

To consider getting a parent professional help, as in putting them into a home, as being non-responsible or non-respectful is to misunderstand intent and purposes of others.  Lets not judge that one way is better than another.  Using personal experience, I can assure you the day comes when parents need help - hopefully this is within your ability to provide in the best possible manner.  

As people are living longer, there is more need to consider the health and wellbeing of the elderly.  It wasn't even a consideration in generations past.  Doing what is best is not necessarily a one size fits all solution.

We took care of my husband's mother for 13 years.  It was no party, but I would not have had it any other way.

its not an easy subject to resolve.everyones situation can be differant.
in this country senior citizens are regarded as a liability by the goverment and population.

i believe senior citizens made this/your country /for what it is, with their labour and standards, taxes paid,which we/you now enjoy.
and therefore should be looked after by the family/goverment, as an asset, with gratutude.
not regarded as a liability or as recyclable material as one goverment put it

what happened to all the wealth these people created, and taxes paid.
surely there is enough for a health care system and pension
maybe the goverment/relatives have spent it all?
and cant wait to get the last on death, samadhi.

but times and values change
free enterprise and world trade and money  and politics has destroyed most family units
without a dollar in ones pocket one is worth nothing, to anyone

one can make more profit from a family of five, by selling them a car in their own house, rather than one car,for one family,in one house.

fortunately where i live there is in a nearby town a free pallative care service provided by volunteers and public, not goverment, support. where people can die in their own home with free care, by volunteers and paid proffessional staff.

maybe this is the ,or one answer, to the challenge/situation

not all families are happy, so wont look after each other
most murders are committed by family members,on family members.

in india some ashrams look after the unwanted

It would appear that the value of life itself needs a little nudge.  Every life has value.  Just because we age does not diminish our value.  

If children are in it for the money - its time to re-evaluate.  I, for one, would see it and leave all resources to others (charity) before supporting such greed.  This, too could do with some re-evaluation of promise.

The caregiver generation is upon us (anyone over 40) because of people living longer and needing care.  The between generation - aiding their parents as well as helping their children.

These are two issues that were not even evident in the original post (or at least my answer) but we may consider....when we age, we need help medically that we sometimes try to avoid taking and/or accepting.  After many falls (which were becoming dangerous to health) my mom was ready to be put in a nursing home.  Before this event, her death occured so it was not an issue.  But, yes, the decision to do so was made by me with all ease and grace - no one in the family could make her take her meds - she was killing herself anyway.

Having seen the state of nursing homes with other relatives, it is not an easy choice - but all old people get to a point of needing help and not accepting from those who care the most.  It is easier to visit your loved ones in their homes (or yours) than a nursing home, if they will listen for their own best good.  I can guantee if we gave mom a choice - it would have been behave for the one who took her rather than a nursing home.
