The following sentence is from a commencement speech.
All the more reason to be grateful, this and every day, that we live in America, where the talents God gave us may be used in freedom.
I don't understand the phrase "all the more reason to" even after I looked it up on thefreedictionary.com, which returns the entry:
all the more reason for (doing something) and all the more reason to (do something)
with even better reason or cause for doing something. (Can be included in a number of grammatical constructions.)
I don't quite understand the explanation: what does "with even better reason" mean?
Can anybody say something more about this phrase?
