There is an imbalance in the ratio of men who are eligible for marriage to women who are eligible for marriage

Marriage squeeze: The term marriage squeeze is described as a demographic imbalance whereby the number of different "potential brides" is not considered as equal to the number of "potential grooms". When every individual doesn't get an opportunity to marry someone then a few people will be deliberately squeezed out from the "marriage market" and won't be able to get to marry.

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.
