The education system seems to have produced more sluts than wife-material sinkie buus.
In the past, many men married because premarital sex was socially unacceptable. To satisfy their basic instincts, marriage was often the only socially approved path to intimacy.
Now educated sluts are available as housemates and travel companions - new vocabularies continue to evolve to reposition premarital sex as the norm. On the ther hand, chaste women are continually being slighted as old-fashioned and unwanted. The phrase "left on the shelves" is a propaganda designed to glorify sluts while desecrating virgin women at the same time.
As social demographics shift and sluts become the dominant species in the female population, the only way to salvation is NOT marriage but a women-free life.
