Every study shows this, and any investment the government makes in home care is done because it's much cheaper.
The longer we can keep someone at home, the better it is in terms of cost. There's no doubt about it.
There is a checklist, which is yay long. There are just so many services--I've gone through this exercise with my own parents--as to cutting nails, taking baths, and all of these things as we age that we can do less and less. With a number of things, we approach a time when it's beyond home care.
That's when spaces in a long-term care facility... We need a home for these people. It's a very relevant issue. This is just the tip of the iceberg: soon there will be a great number of people who cannot be cared for any more by their natural caregivers. What's more, there are no spaces. Waiting lists are already very long.
