Kids are like a white paper, experience is what makes a kid “stupid” / “smart” or just to who they are.

But yea, I agree, that many adults have not the education they would need to educate a kid properly. There should in my opinion be support from society (like with government founding) that ensures parents can get educated enough. The society would profit highly from such efforts, I think, as well educated people can look after themself and are less likely generating costs that society (through taxes) has to pay compared to less educated people.
