The way we're treating the planet we live on, this type of society will crumble. How it happens I don't know. Even generations close to each other can have really different values, so things can change. Maybe, if we're lucky, we will not crash and burn, but gradually learn a new way of being. The religion of self worshiping and gluttony will not last forever. It will be "in" to be loyal and have a sense of duty. Minimalism will also come back. The way we live, it really has to.
You are young, so you might see positive things within your lifetime. There will be a time of change and struggle. But things will just not get worse and worse and worse to no end. Sooner or later things change in another direction. Change is the only thing we know will happen really.
People need to reconnect with nature. It sounds all flower power but nature is both giving and cruel. When we reconnect with nature we might start to heal as a society. And on a personal level.
