Every person living in an independent Scotland should be paid up to £15,000 by the state, it has been suggested.
The Scottish Green Party claims a “citizen’s income” would tackle inequality, poverty and unemployment.
It said the policy – a right of citizenship – would guarantee a wage for everyone regardless of what they did.
The idea is contained in a new document outlining the party’s vision for an independent Scotland which was published yesterday.
Deputy Conservative leader Jackson Carlaw said: “The ludicrous idea of handing people a £15,000 bribe is beyond unrealistic.”
But the Greens insist that the policy could be paid for by reducing tax allowances and means-tested and contributory benefits.
The amount paid to people would be related to age, with older people receiving more than adults of working age.
A spokesman for the Scottish Greens said: “A citizen’s income is one way we could tackle inequality, poverty and unemployment.
“It would cut bureaucracy, encourage valuable voluntary work and support creativity and enterprise.
“By taking full responsibility Scotland has a chance to explore such ideas.”
Mr Carlaw claimed the policy document represented a “crackpot charter that exposes the sheer madness that besets the Yes campaign”.
A spokesman for pro-UK group Better Together said the Greens’ opposition to SNP policies suggested the Yes Scotland coalition “was falling apart”.
A spokesman for the SNP dismissed that notion as “nonsense”.
He added that the white paper being published by the Scottish Government later this month would set out what an independent country would look like.
