If Matt Goodwin wants to know why women are not having chldren/having children later perhaps he should read what Farage has said about women and fertility.
"I've noticed that the women that tend to get to the top and the women that tend to command the highest salaries tend to be women who haven't had families,"
"I think the reality for women in the City is that if they have children it has a very detrimental effect on their future pay prospects."
"I think young, able women that are prepared to sacrifice the family life and stick with their career will do as well if not better than men."
"If a woman has a client base and has a child and takes two or three years off work, she is worth far less to the employer when she comes back than when she goes away."
"there are other jobs in which if you take six months off and come back you find yourself behind the rest of the pack and earning less money. That is a fact of life. It’s difficult to change that,.”
The Reform message is - Women must have more babies and have them younger. Women must also expect to earn less. Don't expect Reform to do anything about the reduction in earnings because it's just fact of life.
Reform do not have women's best interests at heart.
