There are trade-offs between past lifeways and current lifeways. Indeed, modern Western culture has many distinctive maladaptive qualities (like forming family group organizations only found in the absolute most resource poor populations... indicating that, though they have access to more stuff, they are actually barely surviving...). Our diet is abyssmal, but it's genetically programmed. We finally have nigh unlimited access to all the previously rare foodstuffs that our bodies are designed to crave, but too much of a good thing is a very bad thing indeed. But, in any case, if you want to compare past to present, present is going to wins hands down for reasons like "penicillin".
From the get go, these questions are riddled with assumptions and unstated terms that makes it almost impossible to answer unless we know what you're basing your arguments on. What does your use of the word "civilization" even mean?
