Choosing more risky jobs may be male biology and the gender equality paradox.
No increase in supply of supportive husbands would significantly increase the amount of women choosing riskier careers.
> Iceland consistently ranks as the most gender-equal nation. It is also the nation where men and women are most likely to pursue sex-typical jobs.[1]
Also does a person truly need a supportive spouse to undertake a risky career? My assumption is that people decide their career paths well before marriage, and some men choose their career to be a more attractive dating prospect.
