The future is very uncertain for a lot of people today and their children. I think it would be great if people didn't have to deal with the complex issue of housing. If good paying jobs were available to everyone so they didn't have to worry about not having a place to live. Just security in the basic necessities of life for everyone.
People should also look out for nature, housing with lots of green space, parks, forests, etc. So that young and old have somewhere to go and spend pleasant moments together.
It would also be nice if people were not so aggressive and mean to each other. To bring a bit of tolerance, respect and esteem not only for the elderly, but for each other in general. To be able to help each other selflessly when needed, to be able to say hello and even smile. Today's life is terribly chaotic, complex, demanding.
It's not easy to make the future better, to make it a little bit sunnier. Learn to solve problems calmly and together. So that parents don't have to deal with health care, like where I'm going to have my baby.
Just to try to calm down situations that don't need to be unnecessarily spiked, so that life itself is relaxed even if sometimes things go wrong.
