jon, think its all in the contract that you take out with the clinic. From what Mrs skip has told me, if your profile sound good, you may be popular and end up fathering more than one child. One may go to a rich couple and the other a poor couple.
As you have no choice in who has your swimmers, its also right that they have no background about you ie how much cash you’ve got. Poor couple want sperm from the richest man there so they can come begging later in life? Not going to happen.
Its not like you can say to the clinic “i want to donate some sperm but i only want it to go to rich people”, so you can go begging to your kid when times are hard.
The child can when they hit a certain age can find out who their dad is but they have no financial come back.
I also think the law changed in that you are not donating sperm for cash anymore either, more of an act of kindness to people who cannot have kids. Mrs skip is currently doing her dissertation on this topic so i get to hear all about this when i go home
