Is it true that most of teenagers are pampered and sheltered by parents and they grow up without any sense of responsibility?

That is some parents and kids, not all of them.

My kids all have age appropriate chores, expectations and responsibilities. I started this when they were young, not when it was too late. Allowance is not a privilege or entitlement in our home, they have to actually earn it. If they want something extra (like a game or something like that) they can save their earnings and buy it.

My kids actually do more than I ever did. I was the youngest and only girl so really I never had to do anything. I still though have worked since I was 15, I still had manners, etc.

My husband, his parents are wealthy. They had a housekeeper and a nanny growing up, but his parents also let him and his siblings know those people worked for his parents, not him. His parents made them clean their own rooms and otherwise do things for their self. As a result, my husband can cook, clean, do laundry, etc.

parenthood is a difficult pedestal to climb.

Most of parents are short of time these days to really teach good values to their kids.

not all of thenn are like that, it depends on the teenager

Yes that seems to be the norm these days.

Later on, the employer complains and usually fires the snowflake.

My parents had me drying and putting dishes away from the time they trusted my ability to stand on a chair. My siblings & I did a lot of chores for very little or no money. We weren't minions. We got rewarded with family car rides that lead to fun adventures which all costs money. I am thankful my parents weren't strict to the point we feared them but just enough to learn manners and behave like decent human beings.

I've had friends whose parents wiped their asses all through high school and never learned or cared to say "thank you" or other simple manners. Good parenting really reflects on how your children turn out to be. I know it's not all cases. But kids don't misbehave from love, they act out from not getting proper love. And tough love to a first child must be heartbreaking in many ways. For that I love my parents for being strong!

Yes a lot of it is down to parenting.

Parenting starts immediately, routine is essential to a baby, and youngsters thrive on it.

Lazy parenting doesnt provide that and saying your child is "sassy" isnt cute, its the first excuse parents of wilful toddlers make.

Leaving parenting until teen years is a HUGE mistake
