> Is there a field that is similar to economics but is empirical and about building working systems rather than just theories, and incorporates recent high tech advances, and accounts for sustainability by incorporating things like finite resource tracking? Yes. It's called "economics". Empiricism is absolutely central to modern economics. Here's the latest AER, the top journal.[1] 7 out of 8 articles are empirical. 4 out of 8 actually use the word "Evidence" in the title; by now this is practically a meme. Incorporates high tech advances: interested in machine learning? Here's an overview for you: https://www.nber.org/system/files/chapters/c14009/c14009.pdf https://www.nber.org/system/files/chapters/c14009/c14009.pdf Accounting for sustainability? First, environmental economics is an entire subfield. William Nordhaus won the Nobel prize[2] for estimating the costs of global warming, oh, and have you heard of the Stern Review? More broadly, the field of economics was famously defined as "Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses" (my italics). Sounds like it might be relevant to finite resource tracking. Lastly, I'm not sure why you think economists support the current level of inequality. I'd wager most don't. Maybe you've heard of Capital in the 21st Century, which put inequality squarely back on the political agenda. It's by Thomas Piketty, an economist.
