I only had the one brother. He had to look after me, being 6 years older. When things went wrong, he was very supportive, that suited him but when things went right, better for me than for him he was difficult.
My GS is an only child and his parents are careful to give him lots of freedom and lots of friends, who all live nearby. Social media can not make up for real friends and real friendship.

my brother chose to ignore me for all of our younger years. When we became adults we were polite strangers. It was only when our mum developed Alzheimers that he began behaving like a brother.
