Why do we think alimony is no longer necessary?

I just read about the Supreme Court of Canada decision on alimony. Here is how I interpret it (this is not a legal opinion!). If you get married in a church or a civil ceremony and you later get divorced, the courts will split all your family assets, caregivers will receive child support, and in some cases one partner (usually the wife) will receive alimony (support or compensation to get her back on her feet financially particulalry if she gave up her her career to care for kids).  In most provinces, but now not Quebec, these laws apply to people who live in Common Law (not formally married but living together for over three years). In Quebec now unless you get married you will get no alimony. Wow. I think I will write an article: “What Women need to know before they Do Not get married.”
