So what makes the world a tough place?
So many things.
Selfishness - the 'I'm alright Jack' mentality so beloved of capitalists who believe that if people are poor it's their own fault for not working hard.
Self-righteousness - the belief that there is only one way of living a good and moral life, and it's yours. This is the path that leads parents to disavow their children for being gay, for instance.
Greed - the need to to accumulate millions that you will never spend, whilst others go without.
Nationalism - the belief that your country and its ways are best and all others are worse, and this is a reason to look down on other people. At worst it leads to things like Brexit and the invasion of Ukraine (and yes, these are different orders of magnitude).
Ignorance - of the wilful kind that means people don't want to learn because it challenges their world view. Climate change denial is an example, environmental damage is the consequence.
All these things and many others, perpetrated and perpetuated by human beings in power, are incredibly damaging and make this world a tough place to live.
On an every day basis on the other hand I see little acts of kindness - I co-facilitate a support group for relatives of people in addiction. I pass on what I've learned from my own dreadful experiences and see people become stronger and happier. It can be even smaller - a compliment to a stranger, picking up something another person has dropped or holding a door, paying for someone's coffee when they're a few quid short, helping a neighbour. There's so much of this, it just doesn't seem to exist in the spaces where the powerful live.
