How many men would like to opt for stay-at-home status if Life demanded?

The other day I was having a debate with one of my very good friend about stay-at-home men. She pointed out that very few men intend their stay-at-home status to be permanent or even long-term. She would argue that 99% of men did not like to stay at home, even if the wife earned more money than the husband in a household; point to note here is the reason she mentioned was not ego but simply for the fact that they are not used to it. Not used to what? Women were not born with accepting attitude of stay-at-home-while-the man-earned. Women cultivated it for reasons that women were best suited to manage homes and relate better with children. I think what is wrong if men stayed at home when life demanded it. Well, maybe ‘wrong’ is not the word. The increasing necessity or advantage of a two-income home nourishes the expectation of husbands/ fathers getting involved in domestic duties. The unique mix of personalities between a husband and wife if played smart would in fact contribute majorly for mutual respect in a couple.
The thought that, for a man to stay at home to avoid responsibility was wrong always frustrated my inquisitiveness. The unanswered question was where to draw the line that defined when a man is slacking and when he's providing for his family. Do any of the following situations project to be an allowable reason for a responsible family man to stay at home:
1) His wife makes a better salary or has better benefits
2) He's better with the kids than she is
3) He can't find work (whether he's actively seeking it or not)
4) His job allows him to work from home, while her's doesn't

These days, when the lay-offs target men in a more relative number than the women, it is a thought to be pondered upon. I remember once at my work place, a dirty debate sprang when two guys mocked the third guy who argued being happy to be at home if his wife earned better than him. He was poorly ridiculed for going against the Indian society norms placing him in a sorrowful state. In the midst of a tough economy, to meet both financial and parenting demands, a sensible choice for a couple would be to fight cultural trend over ego. I believe that the culture should become more gender-neutral, male/female roles should become less of a determining factor in parenting and work.

But I know for a fact that Indian women of a male dominated country would have to fight for many more years to come.

One thought men can ruminate, is making their daughters/ wives more independent & strong and their sons or themselves more adaptable to fostering their thought process in a gender-neutral manner.
