When we deny the poor and the vulnerable their own human dignity and capacity for freedom and choice, it becomes self-denial. It becomes a denial of both our collective and individual dignity, at all levels of society.
When people gain income, they gain choice, and that is fundamental to dignity.
If indeed we can create systems that allow individuals to access goods and services like health and housing and energy and water, in a way that they can afford, they'll all have greater choice, greater opportunity, greater dignity.
