In this vastly overpopulated world, and yes it is, quit denying it is, habitable land is in short supply and land to grow and graze on is too. So forget any daft notion that the planet isn't vastly overpopulated because it is.
People who get married get a special day where they get showered with gifts and money, they are celebrated and when they have kids the same thing happens again. Yet single people who decide they don't want to contribute to the overpopulation problem are shunned, never invited to anything and never get a special day or tax breaks like married couples do.
The whole thing is wrong. Single people with no children are the ones who should be being celebrated instead of people asking when you are getting married and when you are having kids. They get cast out and abandoned by almost everyone.
If you truly want a better world for your children, be very thankful to those who have forgone their right to have children for the sake of yours, instead of acting like entitled pricks who think they are more special because they had sex and made polluting little egofruits.
