Q: My wife and I, both 80, are comfortably retired with no debts. We do everything we aspire to including generous giving, volunteering and a lot of travel. Contrary to the usual advice, we are invested for long-term growth with the goal of bequeaths to our descendants and charities. Although our country’s economic health over the next 10 to 20 years seems uncertain, we have been unwilling to give up on potential growth of the kind we enjoyed over the past 50 years. Are we on the wrong track?
