I think about this constantly recently. 

Once you have kids - why tf do you do anything if not for them.

How could you earn a small fortune and not want your kids to have it?

(on the other hand - i see the drawback of giving them so much that they could never feel productive.) 

 If you are thoughtful in how you raise them then I don’t think money will ruin them. 

 Fund their entrepreneurial endeavors not lavish lifestyle basically 

 Exactly. Provide a safety net but expect them to get out and compete and win. 

 Well said. I say kick them out at 19 and bring them back at 20. They'll be grateful for what theyre given and have that real world harsh experience.
