Greediest age or a plan to tolerate the other’s views (5,2,8)

I believe the answer is:

agree to disagree

I'm a little stuck... Click here to teach me more about this clue!

'tolerate the other's views' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'greediest age or a plan' is the wordplay.
'plan' indicates an anagram (plan can mean organise).
'greediest'+'age'+'or'+'a'='greediestageora'
'greediestageora' anagrammed gives 'AGREE TO DISAGREE'.

'to' is the link.

Can you help me to learn more?

(Another definition for agree to disagree that I've seen is " Drop unresolved argument".)

I've seen this clue in the Sydney Morning Herald.
