You don't need to be a millionaire or need 9 hours to play golf. I used to have a game on an evening with my dad in the week, we were not at all wealthy.

My buddy is a teacher in a poor district. He joins a golf league every year. Plays weekly at least when the weather is decent. My uncle plays weekly. Several guys on my softball team play. Not one of them has a million dollars. I play every few years or so. With no equipment meant it runs me $30 to $50 depending on where it is. Would be less if I owned clubs, or had a membership... haven't played since the pandemic, so I am sure the price has increased, but plenty of people spend more on drinks for one weekend.
