Why can't you understand why parents provide housing when their children get married?

Is it because the core group of the bullpen is aged 45-55?
Due to the real estate explosion in the Seoul metropolitan area, unless you are a professional or work at Samsung/Hynix,
it is difficult to get into an apartment in Gyeonggi-do, let alone Seoul.
Even new developments on the outskirts of Gyeonggi are priced at 800 million won..
That is why it has become common for the current parent generation
to aggressively support their children.
As a result, "bullpeners" in their 45-55s who experienced the era of inflation
cannot understand newlyweds who move into Seoul metropolitan apartments
with support from their parents,
and I feel that even the parent generation—who knows better than anyone
that the first real estate purchase is crucial for wealth building—
cannot understand the parents who are being pushed to the outskirts of Gyeonggi
after providing housing for their children.
