Social Justice in my mind

There is no true equality in the world. Some have advantages over others.
Physical, mental, social
Some given, some inherited, some paid for, some worked for
Instant or over time

Regardless
There should be Equal Opportunity in all areas.

Communities should ensure those within have their basic needs met.
Affordable access to safe shelter, healthy food, adequate health care, transportation.
Participation in creating and enforcing laws.
These things ensure the health of a society. If a group of people don't have these things, they negatively affect the rest of society.

Power

Leadership is the art of getting someone else to do something you want done because he wants to do it.
Dwight D. Eisenhower

Power is the ability to get people to do things they wouldn't choose to do on their own do.
