This is a great resource. I'd nitpick that the childcare expense is IMO a terrible evolution of society. People used to take care of eachother's kids while they were at work (eg, work less hours or compressed days and trade day care days with a friend. ). It's far better for children to have stable adult support (ie same small set of people stably over time) than a revolving door of new employees, whomever is working that shift etc. So we're being less resourceful _and_ giving a worse setup to the next generation.
children used to just go to the workplace with adults and/or spending time nearby playing with other kids. it's the separation of children from adults that creates a problem, not the accounting of it (e.g., childcare cost figures), an extension of a victorian sterility to public life, trying to cast perfect images of idyllic lives for others to admire rather than living carefree.
Most of the historical community building was done at faith communities, and by stay-at home parents in the past. As a society we fell hook line and sinker for "The two income trap," and are unwilling to contemplate the horrible idea of allowing families to collect the childcare subsidy to pay the parent providing childcare is upsetting to enough different groups to be a non-starter.
Right wingers are upset because "it's socialism" and folks on the left who I've discussed the idea with have repeatedly expressed fear that it will undermine feminism.
