I did not read the article, but, at some extent, yes, inflation does intensify economic inequalities. It's not difficult to see it actually. Don't you think the variables "level of income" and "percentage of owned assets in the form of government currency or an equivalent" have any sort of relation?
In general the most poor are those who lose the most with inflation.
The new money is not distributed equally. Banks, for instance, receive it before most others.
Did it mean, that without them, there will be no inequality ?
No. Not in any way.
PS: Well, i am agree that they intensify that process.
I am desagree (and author dont mean that too), that there will be no inequaliti without them at all
