This is abolutely a fair criticism of the terms I've been using. I don't mean to imply that zero production happens outside the paid-labor economy, or that the two spheres we're discussing don't depend on one another and intersect in deeply significant, even vital ways.
How about this: Instead of referring to the paid-labor economy as "the economy," we can call it the "external economy," if you like, and the other sphere the "domestic economy." Together they make up a "total economy." Doesn't change what I'm describing, we've just decided to use new words. Now, assuming domestic equality, ie the husband isn't beating and exploiting his wife, the rewards of the work you do within your own household accrue directly to you and your loved ones in a more or less fair and equal way, and vice versa. This labor doesn't feed directly into the external economy, and hence does not deserve remuneration from said external economy.
Imagine a household where all the occupants did, without working in the external economy, was fix up the house, do landscaping, go shopping, rearrange the furniture, wash the dishes etc 30 or 40 hours a day. Should this family be paid for all this cleaning and yardwork? I would argue no, since they are "paying" themselves already.
Naturally, we could make laws providing for certain kinds of need that relate to the domestic sphere. For instance, we might provide extra income, child care or a reduced work week for single mothers and fathers, parents with children who have special needs, that sort of thing. No conflict with parecon that I can see.
Now, as Pareconists often point out, Parecon is primarily, in fact almost exclusively an economic vision, or, to use terms you would probably find more appropriate, a vision for the external economy. It's not a total vision for every aspect of the society, and so, as I understand it, has little to say about domestic life, but focuses instead on what we might call the non-domestic economy, the external economy, whatever you like.
And that, I believe, is my limit for the day : )
