I think parents of today, who have limited the number of children they bring into the world, have doted far too long and hard on their offspring, They have instilled 'greed' in their progeny and deserve the payback.
I wouldn't be surprised if the rate of only child families are higher than ever.
When you do genealogical research, it's chilling to compare the sizes of families back 100+ years ago to now.
"Large" families back then meant more than 14 kids.
And you're right, these singles are hopelessly spoiled.
When my children were younger sometimes ( as in everyday) one or the other would start blathering about "mine, mine, mine. I full of understanding and sympathy for their delicate egos would tell them. " Nothing in this house is yours. Your father and I pay for everything. We are nice enough to LET you use some of the things we buy. But until you show me a receipt or your names on the mortgage. It is all ours." When they would ask about an allowance I would say. " I allow you to live here, I allow you to eat the food I buy, I allow you to wear the clothes I buy." If they wanted money they were given EXTRA chores to do. I was nominated for Mean Mommy of The Year quite a bit.
