With birth rates decreasing, there will be less people like the OP to take care of their elderly parents. I wonder how people with no children will fare in a world with no support system in place for them. In 40 or 50 years things will be very dire if nothing changes.
Personally I feel its insanity to be experimented on with a cocktail of medicines in the last parts of life when there are more important concerns to spend money on for people at the beginning of their life and I think its selfish to hang on if you are not contributing in someway but I'm sure others will see things differently.
I fully support the work of Dignitas http://www.dignitas.ch/?lang=en and I see other countries are slowly beginning to make euthanasia legal. Unofficially some Dr's do give lethal cocktails in hospitals in some circumstances but its not spoken about because laws prohibit Dr's from doing this. Alot of people I have spoken to think its the Church and religious followers preventing euthanasia from becoming legal and thus creating this perverse situation where people are tortured on a cocktail of drugs keeping them alive.
I also know Nurses have been known to meter out their own justice to patients in nursing homes and hospital wards based on rumours or gossip and many blind eyes are turned because these are Nurses!
Another interesting development being seen is "no fuss" or direct cremations are becoming more popular with the elderly. Basically, no service at a church or crematorium, its just a simple collect the body, paperwork completed and then the body is cremated.
Personally, if I had a cremation service when I go, when the curtains go down and the coffin disappears off to the burners, I'd want this tune playing!

I think it's more accurate to say, kid's may not be in a position to do it all.
I just went through this with my mom. She needed 24/7 care that I couldn't give her. Thank God we had the resources to get her into a "good" place. It was $5k/mo for 300 sq ft in a very low cost of living metro.
