How would you feel if you knew I lied to my kids and they believe the world's fair but I only prove that the system was rigged?
Do you feel okay about lying to them?
I know my children will discover the truth on their own
You shouldn't lie to your children. It's better to let them experience things on their own instead of manipulating their expectations. It might be harmful for them later.
They will find out the truth no matter what I do. I know it's bad but I want to teach them about the world.
Regardless if they find out the truth or not, it's wrong to lie to your children. You should be honest and upfront with them and that will instill honesty in them in their social lives.
