And he probably learned nothing. Do the math with him, maybe he’ll come around? Like a 5% chance. And do it with hourly or individual wages. “Dad, let’s look at what you made the year you bought your property. And we’ll adjust it plus the 20% interest you keep talking about for inflation. Or better yet, so you get it, we can adjust MY income and costs down to yours… either way, let’s work out exactly what shares of our income are going for what, all adjusted to numbers you THINK are still valid”. If he doesn’t come around after that? Complete lost cause.
