I know the phrase of the title means that the thing is now easy. But,can this writing structure be used for other adjectives? For example
I have never been busier.=I'm now busy.
She has never been more beautiful.= She is now beautiful.
After the car crash, going to school has never been tougher.=it is now tough.
Is the above understanding right?
Next,when we want to use the sentences like this,is the structure "present tense+comparative" needed?
Finally, what is the difference between the following sentences?
A.It has never been easier.
B.It has been easier.
C.It is easier than before.
D.It is easy now.
