I stayed at home while my children were small (in the 70's) because I couldn't afford to pay for childcare. I didn't feel stifled or held back in any way, because I have a mind and a brain! I read. DH worked at 2 jobs (both quite mind-numbing, come to think of it, but this is what he did to keep the family clothed and fed). Once the children were a bit older I was able to get into work/college, etc, and it was easier to find childcare (mainly friends - we all helped each other out that way). Some of the jobs I did in the early years of getting into employment were actually dull - and I have to say, were mind-numbing, if you consider that sometimes the main topic was how expensive soap powder/mince/margarine was in this or that shop. The only type of work that was open to me at that time was factory work and heads were down at all times, trying to make enough money to make a difference at home again. So - I suppose I may have been better at home, in that case, Silverfish, because the people I worked with were working flat-out, trying to earn a bob or two extra, and there wasn't any time (or inclination), to discuss matters of the day, the state of the country etc. I know I was capable of something more mind-stretching, but it wasn't available to me then.
Perhaps you needed the stimulus of working, Silverfish - I didn't. Before I went back out to work I had the imagination to be able to understand the reason for the strikes of the early 70's, by reading and discussing the problems that the country faced with like-minded intelligent friends. Meanwhile, my DH contributed to my lifestyle by paying enough taxes in his two jobs to fund it.
