Here's another reality, those like you on the left are working to create a utopia that will never exist, those on the right are trying to go back to a utopia that never existed, in the meantime everyone else has to suffer from both efforts.
Striving to 'create a utopia that will never exist' though leads to people simply working to improve their lives. It is the child of hope. Of something better. A human yearning that goes back to the beginning, this isn't a political thing it is a human thing. A natural desire to have your offspring be safer, better fed, more educated, less fearful.
There is no such thing as perfection, but the striving for perfection is the Saturn 5 rocket that lifts us to the moon.
