There aren’t enough resources to go around and look after everybody’s needs.
Because of this: people can’t get what they need to survive and thrive
Some people will have more because it’s meant to be that way.
You have to fight to make sure you have enough.
Other people (migrants or the disabled or pick anyone that isn’t you) are stopping you having enough.
Even if you want things to be better you’ve been told that there is no alternative to being impoverished and living in a world that gets shittier every day. The blessed millennials subject to so much silly abuse by people who should know better can see this, they know that the world that they’re going to inherit and the world that the people coming after them are going to inherit, is pretty doomed.
The truth
We live under the capitalist system.
It has created the most productive and powerful technology ever devised for making the things people need. But the system of manufacturing and so on is unrelated to who owns it and we have to be careful not to credit capitalism itself with this.
