We live in the best times ever. Life is just getting better all the time. There have always been stupid ignorant people, and always will be. I find the majority of people I interact with to be friendly and helpful, be that out in the sticks or in the big city.
When I've visited the US, I found the people to be friendly and hospitable to a fault. Over here I've seen / attended several road traffic accidents and always there is a surfeit of people stopping to help or assist.
Life, and the world, is what you make it.
