Don't need or want your children to subsidize my golden years. I don't need it, I planned ahead and made wise decisions years ago. 
You can claim a mighty and lofty goal of the future... when you also fail to pay for children's education. I pay more for them than you do.. and I'm the bad guy. 
If your children are expected to make so many advances.. you should be proud and contribute more to that future endeavor of success. Not use it as a weapon of hate. 
Get over yourself, man up and pay up. Your kids... depend on it!!!
