You found a cure for psoriasis

You cannot save the world.

People suffer every day everywhere around the planet. It'll never stop. P is just one area and there are of course many medical conditions that cause suffering.

So, you could argue that giving away the cure will help P sufferers, but it will only help those with P. But with all that money you'd be taking off the giant corporates, you could give it away to other medical sufferers.

Where does it end ? Can you save everyone ? No, is the answer
