This problem you've identified faced by disabled people won't solve until (certain) people get concerned. When society starts to care about the development and wellbeing of these dear ones then they can be adequately taken care of. To be sincere caring for the needs of some of them is not going
to be possible in many countries for years to come. In this case the burden falls on their parents and relatives. Others who are concerned can help by creating tools and innovations that can aid these people.
Thanks for your thoughts. Have a great day.
Thank you for your comment.
I still hope that eventually society will be kinder to people with special needs.
