1. Why does science fiction so frequently portray the developed nations as ruthless, evil and warlike when the opposite is the reality in most cases?
Okay, let's ask a serious question.
What is the difference between the USA and the DRC? What is actually the difference?
Well, the US has 850 times the nominal GDP of the DRC, and 130 times the nominal GDP per capita. The US consumes 1,800 times the amount of oil consumed by the DRC. The average US citizen has double the caloric food intake of someone in the DRC.
For context, the DRC is probably the most resource-rich country on the planet relative to its land area. It has incredible mineral wealth, and yet the people living there see almost none of the proceeds.
Have you considered that maybe the reason the US isn't particularly warlike is because
it has already won without needing to fight. The US doesn't need to go to war to get the DRC's shit. It already gets it. The entire planet is based on a financial system in which the top 10% of the world drinks everyone else's milkshake, and on the rare occasion that has been challenged, on the rare occasion there is a serious threat to a resource on which the developed world is dependent, the result has almost inevitably been war.
But generally, the US has no need to go to war because the status quo already gives the US (and other developed countries, I'm not leaving them out) everything they could possibly want, while their counterparts in the developing world are forced to buy guns from said developed countries in order to fight proxy wars over the pitiful scraps left behind.

2. Why does science fiction so frequently portray a negative future, when by all long term global trends of well-being, we are the best we have ever been and are getting better with each passing day (as a whole, humanity is about 50 times wealthier than we were 1000 years ago)?
This is true. It's even true in the context of what I've said above. However, there are serious questions about whether this level of consumption is sustainable. The massive environmental and resource cost of supporting even a small section of the world in the lifestyle to which we have become accustomed is already causing damage which is probably going to irreparable, and there is no evidence at this point that the expansion of the developed world is going to bring any respite from those costs. There is enough food producing land on the planet to feed the 10 billion people the world is probably going to end up supporting before population growth caps out. There is not enough food producing land to feed 10 billion Americans, and this is before we factor in the possibility of serious environmental crises.
Short of some magical technological solution to all our problems, which is ultimately what "progressive" science fiction relies upon, people cannot get perpetually richer for ever. There is a big ball of dirt we're all sitting on and it only has limited land, limited resources, limited suitable climates.

Wars cost more than desalination. Wars will never be fought over water when you can make water cheaper than you can make war. Even trying to find a historic war that was specifically about a resource is difficult. The only one I can think of on the spot is Iraq's invasion of Kuwait in the 1st Gulf War.
* French & Indian Wars (mostly fur)
* Japan's entry into world war 2 (oil and rubber)
* Opium wars (silk, spices, tea)
* Portuguese invasion of Malacca (spices)
* Spanish conquest of the Aztec and Inca empires (mostly precious metals)
