Advances which permit this norm to be exceeded - here and there, now and then -
are the work of an extremely small minority, frequently despised,
often condemned, and almost always opposed by all right-thinking people.
Whenever this tiny minority is kept from creating, or (as sometimes happens)
is driven out of a society, the people then slip back into abject poverty.
This is known as 'bad luck.'
- Robert Heinlein
