Every <div> you add increases your hourly salary by $1.

But really, it's frameworks that do this. I use Material UI at work, and the simple login page I did for the project I'm working on now has six nested <div>s just for simple positioning of buttons when using MUI's layout components. In comparison, the latest versions of Postmill, where I did all the HTML/CSS from the ground up, has a maximum of four nested <div>s in direct succession.
