I'm sure most of you have seen "The Man Who Planted Trees". If you haven't, you should check it out.
Each of us should dedicate our lives to planting white families. What I mean by this is that we should always be providing financial incentive to white couples to have more children, whenever we can afford to do so.
An example of this would be to rent out a house to a young white couple and, during the interview, tell them you like to support nice couples and families like them so you'll allow them to live rent-free in the home as long as they have a child under 3 years old.
The wealthier you are, the more incentive you can give, such as adding that if they have 6 children, the home is theirs free and clear.
Another example would be to set up a foundation that gives grants to white couples, the grant amounts being a super-linear function of the number of white children they have.
1 child - $1,000
2 - $3,000
3 - $10,000
4 - $30,000
5 - $100,000
6 - $250,000
7 - $500,000
8 - $1,000,000
They can update their payout by getting the difference between what their current status would pay and what they've already been paid.
Then publicize the foundation and take donations to fund it.
Ideally, whatever you do would be self-sustaining or even snowballing, like a Ponzi scheme. Except, where a Ponzi runs out of participants, you never do because you have new participants being born all the time, by the very nature of the scheme.
An example of self-sustaining would be to make your white families well off but require them to make payments to you thereafter.
Give your gifts in lump sums whenever possible because one needs money to make money, and you want them to become wealthy, not just for payments back to you but because it empowers our race.
