I think your points are good, Himalaya. Plus, I feel I have to keep stressing that I agree parenting is undervalued (or not-valued) and that caring in general deserves a higher status. It pisses me off as much it does everyone else that a footballer can earn the salary of 1,000 nurses.
If I keep on putting arguments against salaried parenting, I risk getting into pettifogging arguments and exposing personal reasons (which, although they apply in general, will lead to misconstruction). So I'm going back to the less-patriarchal business structure.
In Germany it is usual for large employers to offer a year's sabbatical for every X years worked. The qualifying period is commonly 5 years - so, for every six years with an employer, you only work five. The employers don't pay the cost of this: it's covered by a sort of employee fund, similar to the way contributory pensions were funded here. Thus, employers do actually support the fund but it's factored down to nothing on their books - I assume they get tax relief; maybe some German accounting whizzkid will be along to fill in the details. Employees set up and run the sabbatical schemes: they're voluntary and depend on a sufficient membership to work out financially.
Basically, it's a structured means of saving up to have every sixth year off work. Because it's structured and supported, nobody loses their jobs and everything is adequately planned. I would like to see schemes like this implemented over here. It doesn't favour parents, but it does allow flexibility to lead a more fulfilling life, in whatever way fits your particular Maslow.
Another, often-proposed, idea is 24-hour business. Personally I think it's crazy not to be open for business 24/7. We're all in a world market these days - if a business only has local customers, the likelihood is that those customers do business across timezones. A 24-hour working day means three 8-hour shifts. That's three times the number of jobs and two opportunities for a worker to fit their job around the rest of their life. Add flexitime into the mix, and the opportunities to create a life that works for your family become infinite. Some workers may choose shorter hours for less pay, others may choose more and so on.
Wrt workers who choose longer hours, I don't really understand why workplace childcare never took off. I know the big company I worked for put it to a vote - they proposed a levy on all employees' salaries, which was rejected, then a larger levy on parents' salaries only. That was also rejected. I wonder if a more concerted campaign, with government backing, would get such schemes moving again? If the tax breaks for employers providing the service have been withdrawn, they should be re-introduced and, perhaps, made bigger.
Part of me thinks that various child-friendly initiatives have fallen at the first jump due to ingrained attitudes amongst the fat blokes who have the veto. I can see attitudes changing very fast among younger people, though, and am tempted to think they could be got off the ground with consistent government backing. The problem also lies in the devaluing of parenthood, which is the topic of this thread. I do think that's changing - and could, again, be moved along faster with both government and commercial support. It's only - what, one year? - since we adopted paternal leave. As soon as the idea takes hold - and doesn't compromise one's career - the better the picture will become. I hope.
