FAQ
Reader questions

Market swings can rapidly change paper wealth, especially for investors heavily concentrated in public equities. Driehaus’s portfolio, tied closely to stock performance, may rise or fall significantly quarter over quarter, influencing who appears at the top of the Illinois wealth list.

Yes. Family offices such as those associated with the Pritzker family provide structured governance, tax planning, and multigenerational wealth strategies that help preserve and grow fortunes across decades beyond any single founder’s active years.
