There is a simple and very easy way to psychopath proof government.
Stop calling it government.

But really, the structures we will make in the future will bring responsibility along with power.
It will bring transparency to all accounts.

And the future will also bring a shift in how we view leaders.
We will elect the most compassionate person.
The psychopath will not be able to win such a race.

With transparency in all transactions, a psychopath will not be able to hide their abuse of trust.
With responsibility built into the system, the psychopath will visibly fail for all to see.

We will learn to see/identify psychopaths and the destruction they wreck.

If you live long enough, you will see this come about.
(and the pyramidal structure of govern-cement that we see today will become a thing of the past)

Now, about transactions...
You do not give and give and give.

Unbalance happens that way.

So, there will be a money in the future that is much more meaningful for keeping track of people's energy exchanges. It is not like anything we have now. It would be like a blockchain attached to a specific individual or family that manufactures something. It isn't money that can be spent and spent and spent. It is an accounting of human energy and a balancing of giving.

In the future everyone will grow their own food.
It will just be what each person does.
Of course with modern equipment and greenhouses, this effort can be less that 10 hours per week.

i know i am leaving out huge pieces so that you can't get a whole view of what this future is like, but such is the problem with putting things in a small amount of words
