Well, our doggie bags go to the dog, because we love her
Something else: DH and I are both onlies. My mum and dad were both one of two, his mum and dad were one of three or four respectively. His mum and my dad both died over 10 years ago, when we were in our early twenties.
We're now in a situation where my FIL is wheelchair bound with rheumatoid arthritis and because of shame about his medical conditions, chooses not to leave the house. He's entirely dependent on others, and his brothers, who helped support him before DH finished his education and moved here, are getting on a bit themselves. One has arthritis and is being treated for cancer, one has a wife with alzheimers. They've both got their hands full.
So what this means, bluntly, is that it's down to us. Social services and the district nursing team will do what they can- they do the daily personal care, the washing, the dressing. All the rest of it- including some help with medications- is passed to us to do. Helping him physically manage his money. Shopping. Cleaning. Cooking. The works. And we do it willingly, because we love him- but there's a cost. The cost is us living in fear of my mum having a bad fall, getting alzheimers, rheumatism, anything that would require a comparable level of support, and us feeling forced to choose between our two surviving parents. Just ONE other sibling in our families would ease that pressure on us. And yes, the UK has a pretty good support network for people like my FIL, but they can't- won't- don't, do it all. This could be you. This could be your kids.
Oh, and in terms of consumption, more than half our family's refuse is created by FIL. The convenience/waste correlation, ime, is most closely connected to those who need that ease of use. That's not necessarily young families, but young adults who are learning independence and those at the other end of their lives.
