What you're saying is false. If by your definition of quality of life, you see is as man being able to live a cozier lifestyle, then no. Profit/competition/war have driven man to do away with the weak and so the strong and best endowed survive. Now we are so well at surviving, we can sit on our sofas, watch our tv's, have conditioned air, etc after we get home from a comparatively easy job for which we probably had the luxury of choosing. Competition is good for man.
You seem to be denying the work/reward of pretty much all of life is flawed for advancing it. Tell that to life, but that's the way it is.
