I am writing this too late to meet MPJ's original group writing project deadline. But she said she might post some late entries from others, so I jumped into the bandwagon. If you have never visited MPJ's blog, I urge you to do so. She is a great writer and pretty cool all around.
My Happy Place is an idealized world, where the gap between the haves and the have-nots has shrunk to the point of being non-existent. Everybody will be middle class, with access to things that are now reserved to the wealthy. In industry, there will not be huge gaps in pay between high executives and the rest of the company. There will be profit sharing on an equal scale to all. The accumulation of wealth will be seen as something obscene. Politicians will not lie.
Healthcare would be seen as a basic need of society, not a business area. Every town would have an extensive library and a performing arts theater. People will be free to embrace their diversity under an atmosphere of tolerance. Multiple languages will be spoken everywhere, and at school children will be taught two foreign languages as a requisite. There will be no fences on the border of any country. Everybody will be free to move from one place to the next. Women would have a one-year paid maternity leave and the guarantee that they will have their job when they come back. All beaches would be public and no construction would be allowed to restrict or block access to them.
You get the idea.
