You do realise we'll never have a TRULY equitable society, right? I don't care if people call me a pessimist, I'd say I'm a realist. From year dot humankind has had those in power and those with zero power, the haves and have nots. We have groups of people that don't like groups of other people for numerous reasons. Unless they start giving us lobotomies at birth, I can guarantee you 100 years from now we'll still have a society that isn't equitable. Politicians will still be coming out with the same old guff (year 2122 they'll probably still be talking about levelling up, more power for the north etc) and people, quite rightly, will still be fighting for a more equitable society.
Those fights should never stop, however whatever the utopian dream is, it'll never be reached. We don't as a collective have it in us. We'll be the masters of our own downfall and all that.
Here's a bit of fantasy ... or maybe not. Can you imagine in decades/centuries to come what it'll be like as we further progress with space exploration. Imagine if the moon was ever colonised. So in a sense we'd have a clean slate on a new planet to 'get things right' in terms of building a truly equitable society. Do you think that would happen? Or do you think there would be countries laying claim to parts of the moon depending on who got there first, who'd invested the most money, who was aligned with who etc?
All the isms will still exist decade in decade out. I'd like to think things are slowly trending upwards in terms of improvements. However in achieving that, if we all need to act like vanilla droids so no one's offended etc, is that really the world we want to live in?
