Obviously, some problems are harder than others. However, many of us come from backgrounds of some privilege. You have a computer and likely have the capacity to program. You speak English, the current language of commerce, and you likely live in a country where capital is available. You were born on at least first base.

That means you're in a position to gather the resources to make a difference in these problems, even if you can't start today.

That's not the point. The point is if you don't like what someone else (not something else) is doing to you, become one of them yourself.
