If you left the kids being what they already are, you are not doing your job as parent. Parenting is not leave the kids being kids, is teach/prepare them to the next phase of life.
This kind of approach is what led us to a society full of adults (on the matter of age) with a kid mentality (running from responsibilities and looking for government support), known as "weak men". 
Now it's time to the "Strong Men" era, and we parents are the responsible to teach our kids how to be their best version and continue what we have started.
