About "rent seeking" and "passive income": Everybody gets old. Technology companies don't hire the old. And in technology, old is > 45. Which isn't that old given that my life expectancy is about 85. So, darn right I'm "rent seeking". And I save like mad so I can generate "passive income". I assume that I will be pushed out of the workforce very soon - and I don't want to live on welfare for 40 years. Nor do I want to be restocking the shelves at Target when I'm 80.
