Anyone feel like being expected to get presents for peoples kids when you don’t have them is excessive?

I haven't gotten a birthday or Christmas gift since before I was 10. Every month is some child's birthday in my family and I'm expected to buy them things and also for Christmas and get nothing in return which is fine but it feels excessive and it would be more understandable if I had children people got for and you just exchanged for each others kids. I don't want to and only do it not to hear peoples mouths. I also only make $18 an hour and these people who I have to get for all their kids and they get nothing in return have more and it's just the way my family is set up
