Savers may be offered tax-free individual savings accounts (ISAs) to invest in schemes to help the poor.
An independent report commissioned by David Cameron, published today, recommends ways companies, funds and individuals can reap rewards for backing schemes to prevent children leading lives of crime and alcohol and drug abuse.
One idea is to involve the 20m people with Isa accounts by offering a £200 rise in the tax-free savings limit with an early intervention Isa, according to the Financial Times.
The Junior Isa, which encourages families to build up savings for when a child reaches 18, could also be invested in the projects.
Profits will come from the resulting lower cost of benefit claims and dealing with crime.
The report by Graham Allen, Labour MP for Nottingham North, will argue early intervention is cheaper and more effective than the billions of pounds spent trying to help rebuild troubled children's lives when they are older.
His report proposes payment by results when private and voluntary groups take on projects commissioned by government or local authorities.
The government is expected to co-fund an Early Intervention Foundation that will promote the philosophy and encourage "early intervention funds" to attract £200m from investors, including the wealthy.
