Am I wrong for treating my foster children like my own?

I'm 61 years old and have been raising children since I've had children (my 3 children, 4 grandchildren and now my great-grandbaby (4) along with 2 foster children(14 and 15. Even though it gets hard, I get pure joy out of it.

Well with my foster children I treat them just like my own. I buy them nice clothes, they are in private school, in church with me in their suits every Sunday and etc. Well recently I bought the 2 foster children an iPhone. According to my youngest daughter she says I can be nice but at the end of the day they aren't mine. Then went on to say it's wrong for me to treat kids that aren't mine like this when I didn't do any of that for them growing up.

My thing is, when my children were their age I couldn't afford to do any of them but I still at the end of the day made sure they didn't go without.

Am I wrong?
(I'm not going to change but it's still nice to hear others points of views)

Added (1). My other children are grown now, sorry if I didn't make that clear earlier.

Am I spoiled if I never had to do any chores?

My parents are greedy and never bought me anything fancy except a computer and an iPhone, but never in 17 years of my life did I had to clean my room and wash the plates or anything. Am I spoiled? I don't think I'm.

Added (1). My mom does it all for me.
