How about gifting your son a book on personal finance? 'Rich Dad Poor Dad' by Robert Kiyosaki is a classic in personal finance literature that he may find interesting. Another great option could be 'The Total Money Makeover' by Dave Ramsey. This book is popular for its practical financial advice and strategies to help people get their finances in order. You could also consider gifting him a subscription to an financial magazine such as Forbes or Bloomberg Businessweek that offer a variety of articles on personal finance management.
