Today you can still buy simple tools and equipment that are very long lasting, or you can choose modern conveniences. Either way, you actually have that choice, and buying either won't cost you a huge percentage of your wages as was the case in preindustrial times in which any manufactured or produced goods were enormously expensive by tendency.
People in modern times have more time for community and family than at any other point in history. This applies especially if they don't pursue the kind of material hamster wheel that many do. Almost anyone wanting to live at the subsistence levels of preindustrial societies could do so today with far less work than the people at that time endured to achieve the same. I think you're grossly understating how hard and long the work hours just to feed a family and literally keep it from death were prior to (at the most) 200 years ago.
As for your last point, the science on climate change doesn't predict the end of the world at all. Go read the IPCC's own worst case scenarios. They certainly don't predict our extinction. What's more, do you really think people in the 17th century felt any ability to plan 7 generations ahead, or easily avoided living in grimly filthy conditions at a level that was superior to today?
