The Mac OS UI isn't made for maximizing everything. That's why there is no maximize button.
It is very inefficient to run every application maximized because it's a waste of space. Hardly any program needs to be maximized constantly, including web browsers. Macs have "smart windows" that adjust themselves to best fit their content using the zoom, or "fit to content" button, which is the green one.
MS Windows, on the other hand, trains you to maximize everything. It's really sad.
