Advice on the matter of spinsterhood
Question

                I am disturbed by the number of women in this society who do not have husbands and I wonder what is the solution?
Praise be to Allah.The phenomenon of 
    widespread spinsterhood (women remaining without husbands) is caused by a 
    number of things, including the following: 

    1 – Demanding too high a mahr, and the inability of young men 
    to bear the expenses of marriage. 

    2 – Girls refusing to marry early on the grounds that they 
    want to complete their education. 

    3 – Girls refusing to get married to a man who already has a 
    wife. 

    4 – Difficult conditions imposed by the wife’s family or the 
    husband’s. 

    The ways to solve this problem are as follows: 

    1 – The girl’s family should look for a suitable man who can 
    make their daughter happy, and not seek to make excessive demands with 
    regard to the mahr. Rather they should look for a man who is religiously 
    committed and has a good character, who will be able to protect their 
    daughter’s religious commitment and chastity, and make her happy. 

    2 – Girls should not refuse to get married on the excuse that 
    they want to continue their education, so that they grow old and reach an 
    age where they can find no one to marry them. It is possible to come to an 
    agreement with their husbands that they will continue their education after 
    they get married. That is easy to do, praise be to Allaah. 
3 –  A girl should not regard a man who 
    proposes marriage to her when he already has a wife as unsuitable for her or 
    unable to make her happy. Many girls refuse to accept a man who is already 
    married, then time passes and they get too old and cannot find anyone to 
    marry them. But Islam and the Sunnah of the Prophet permit a Muslim man to 
    marry up to four women, on the condition that the man treat all his wives 
    fairly.
