Quick answer
Two sons and two outcomes, and the second line names what actually gets spent. The verse is about where a life's resources end up.
Read both lines
The first line joins the book's long refrain about a father's joy, running from 10:1 through 23:15 and into 27:11, and the verb is loves rather than obeys, which is the distinction this book keeps making. Wisdom held as an affection rather than a rule.
The second line does not moralize about the harlots and does not need to. It reports the accounting: יְאַבֶּד־הוֹן, he destroys wealth, and the verb is total. What the pairing implies is that both sons are spending something. One is spending attention on wisdom and the father gets joy; the other is spending an inheritance and nobody gets anything. The verse also declines to say the second son is unhappy, which a moralizing version would have added. It reports only that the money is gone, and leaves the reader to notice that the first son was never described as spending anything at all.
