>That domestic labour ought to be recognized as real labour, and as such, be paid.

Who would do the paying in this scenario? The children? Aren't they (the children) ultimately the beneficiaries of the aforementioned labour - in the same regard as an employer is the beneficiary of an employee's labour?

I don't understand how that premise would work-out - unless you had a system, like the social security system in the states, where the current generations are paying for the prior; however, even as that system demonstrates, it would eventually become insolvent as the population growth continues unabated.
