Conservative proposals to encourage marriage would increase the income of the poorest families by as little as 0.03%, the Institute for Fiscal Studies have estimated.
Under the plans, married couples where only one person works, would benefit by "up to" three pounds a week.
The biggest beneficiaries will see their income increase by just 0.18% whilst couples where both partners work will see no benefit at all.
According to the IFS:
"The average gains are small because the policy affects only a small subset of families."
And within that small subset are couples with no need for an "encouragement" to their marriage at all:
"If encouraging marriage is seen as desirable primarily for the impact that it has on child development, it is not clear that a policy where pensioner families make up more than a third of the beneficiaries and receive 31% of the gains is well targeted. In fact, only 35% of the families who gain from the policy have children, and only 17% have children under 5."
As the Times editorial puts it today:
"This is surely no time to be giving money away so that people can just carry on doing what they are already doing, namely being married."
As pointless money-burning policies go it seems hard to beat, although no doubt the policy will be paid for by much larger cuts to tax credits, and child trust funds.
However, the point is that it's a symbolic policy which "sends out a message" to the electorate.
Like Boris Johnson's precept freeze it symbolises how the party wants to be seen, even if the reality is the total opposite.
For another example take a look at the Conservatives' new "three strikes and you're out" benefit fraud policy
It's a tough, message-sending, Daily Mail pandering policy, which in reality will affect "zero. No-one. Ever."
I think that's the clearest message about a possible Conservative government we're likely to get any time soon.
