I think it's just arrogance to downplay the struggles of our ancestors while living in the comforts of what modern civilization can provide. Yes, their priorities were basic and straightforward to achieve but this entailed some skills and responsibilities that pushed them to become efficient with their limited resources or they die trying. You don't have to go hunting for days to provide food, a convenience store is nearby to satiate your hunger. You can have all the sex you want provided you don't get killed by competition within your tribe or outside your tribe. Now you can just pay for sex and not bother with mating rituals. People were prone to diseases back then and they had little choice on the matter in contrast to how much we can have an assortment of antibiotics today.
