I am confused with the following sentence in a English learning book,
Society doesn't pay enough to old people.
Why there is no article before the word "Society"? I found in a dictionary that this word can be used as a countable noun or an uncountable noun. So, my guess is that it should be regarded as an uncountable noun here. Can someone verify this? And if so, why it is treated as uncountable in this case? Could the sentence be like,
The society doesn't pay enough to old people.
Societies don't pay enough to old people.
Is there any difference between this three sentence? And how should I know when a word is countable or uncountable?
