On the surface, the idea to create more realistic (like in physics!) and pragmatic economical models looks very appealing. However, in reality it will not work because of very simple reason – physics deals with still nature while economics deals with relationships between us, humans. Thus to create any working economical model, we have to understand ourselves on the first place. The history of medicine (psychiatry, for example) clearly shows that we really don’t know ourselves well enough to build any “realistic and pragmatic models”.

However, there is a solution to many if not all of our economical and other problems. I’d suggest reading what Michael Laitman has to say about it. Just check this link http://www.laitman.com/2008/11/economics-needs-a-scientific-revolution/
to learn more about alternative solutions.
