Children that abandon their parents are called jerks, or maybe you can call them bastards. Any bad names that you give them, they deserve it. Abandoning your parents is A CHOICE, not a mistake. That's why you should not blame anyone for your own fault. Don't give people stupid reasons like 'Oh, i'm busy with my job. How am i going to take care of my parents? '. If so, your parents can choose to say ' I'm busy with my job, how am i going to take care of my kids? ' and just send you to the orphanage. But did they do that? No. In fact, taking care of a baby is way harder than taking care of an elderly people. Baby poop and cry almost all the time but they still bare with you. And you, if you are busy with your job, can't you just hire a maid to take care of your parents? Is it that hard?
If your husband or your wife refuse to to let you bring your parents along when they are sick and need to be taken care of, then just dump your husband/wife! You have to remember that you only have ONE mother and ONE father whereas husband/wife you can get it anytime. Of course, i am not asking you to cheat on them. Just leave them! People who doesnt know how to take care of your parents, won't take care of you when you are old. And think twice before you send them to the old folk's home.
Maybe one day, your kids will treat you the same way like how you treat your parents. Some people who become rich when they grow up will sometimes send their parents to the old folks home because they think that their parents are useless and will embarrass them. No, this is not how it should be. A good parents
