I fully understand what she means (I'm not an idiot) - and I think the way people describe "morals" is very vague to the point of being useless, as correct human actions can be easily enforced using other means (for example we have laws not to kill each other - Why? Well you could say it's the moral thing to do - and of course people say that. But it's also such a waste - everyone would live in fear and nothing would get done if this wasn't enforced - Murder is just economically bad, as is fraud, rape, abuse, battery, censorship and many other things - morals need not come into it - not enforcing these protections is more expensive - for more treatment in thinking like this see "The Selfish Gene" by Richard Dawkins).
See the problem with the terms "intrinsic worth" and "dignity" is that they are almost meaningless and very fuzzy. What do you mean exactly?
> “All lives have equal value”
Melinda Gates repeatedly emphasized the Bill & Melinda Gates Foundation’s deep belief that all lives have equal value and everyone should be given the same chance.
I've come to the exact same conclusion that she has with harder terms. We need to give people the same chance because if done so - we are all better off.
