Why low-income professionals are often targets of "Pong-pong" marriages

When a beautiful but penniless woman dreams of upward social mobility through marriage,
the reason a professional without significant wealth is the best target is because
sons from wealthy families are usually blocked by their parents,
or even if the man overcomes this,
he eventually yields to his parents due to inheritance issues.
Self-made men live such rugged lives like weeds that
they never fall victim to "Pong-pong" even after marriage.
However, professionals from middle-to-lower class backgrounds
earn good money but have spent all their time studying,
meaning they lack experience in dating women.
Furthermore, even if their parents object,
because their profession allows them to earn well on their own,
there are many cases where they easily overcome parental opposition.
Additionally, they are often naive and out of touch with how the world works,
making them the type most susceptible to "Pong-pong" marriages.
You probably think it won't happen to you,
but when a woman is beautiful, men lose their minds as if possessed.
