Now and then I find myself feeling sorry for politicians.

After a good night's sleep the mood usually passes, but not in this case. Last Saturday, Alex Salmond made one of the most attractive offers womankind has heard on these isles since the day we won the vote. In an independent Scotland, he told his party conference, support for childcare costs could rise to levels found in progressive countries such as Iceland, Germany and Finland. Where at present the government meets around 25% of these bills, in the new Scotland this would rise closer to the 75-85% enjoyed by these more enlightened societies.

Such a declaration should have been cue for celebration, or at least conversation. But because many of us suspect every political stance of being an act of calculation and manipulation (and who can blame us?) this revolutionary proposal, what Salmond called a "transformational shift", has led to accusations that the SNP is shamelessly trying to entice women – who up to now have shown every indication of refusing the independence fence – to bite the honeyed carrot, take the leap and vote yes.

One can see why Salmond might be feeling desperate. According to the most recent poll, men are twice as likely to vote for independence as women. This, it has been said, is the product of that rambunctious chemical cocktail known as testosterone. But putting aside hormonal men, what self-respecting woman would like to think biochemistry influenced her decision at the ballot? The women who championed the cause of Scottish independence in its early years – and those in its front line today – would turn puce at the very thought.

I am surprised, though, that prior to Salmond's offer, only about one-quarter of women favoured independence. There seems to be a perception that the SNP's aspirations are inimical to women's best interests, that those in charge of the march to independence are gung-ho. Tell that, I suggest, to Wendy Wood, one of the founders of the National Party of Scotland in the 1920s, or to glamorous Winnie Ewing, whose by-election victory at Hamilton in 1967 was crucial for the SNP's fortunes. Nor were they exceptions. Since their day there have been almost as many inspirational women as men in the ranks of the SNP and the pro-independence lobby, the most notable of whom today are Margo MacDonald and Nicola Sturgeon.

Quite why so few women are drawn to the notion of a separate Scotland is puzzling, given the calibre of these politicians. Matters are perhaps not helped that when Sturgeon began to make a name for herself as an astute and indomitable political figure, she was often referred to as a nippy sweetie. Had she been a man, her sharp tongue, quick mind and refusal to be patronised would have inspired respect. Though Sturgeon's manner has mellowed with time, what she was, and remains, is feisty. In this age, and the one that may soon be upon us, Scotland needs feisty women as never before. This is not a time to be a shrinking violet. That fact, indeed, is implicit in Salmond's child-care initiative.

I am still unsure how to vote come autumn 2014. Slashing childcare fees will not change my income, but it would radically affect my hopes for a better society, and a fairer place for women, whether they are mothers or not.

From almost every angle I'd say this is a tantalising idea, because if childcare becomes affordable, the impact on families – and the entire country – would be incalculable. At last, it will be possible for women to fulfil their career potential, should they so desire. Years spent in education and the workplace will no longer be lost, nor relationships ruined because of resentment or hardship. Almost as vital is the signal such a move gives about the importance of women in our culture, economically, socially and politically.

Salmond's statement may, of course, be pure politicking, the result of necessity rather than conviction, though I prefer to think otherwise. Whatever the truth, it is very welcome affirmation that in the years ahead women could be seen as every bit as valuable and precious a natural resource as oil. And unlike that, it's unlikely we'll ever run out.
