# Why will inflation raise sellers' purchasing power?

According to my textbook, in the chapter on inflation,

"When a price rises, buyers of that good must pay more, but sellers get more revenue when they sell it. The loss in buyers' purchasing power is matched by the rise in sellers' purchasing power."

I understand the part of falling purchasing power for buyers (since each dollar can now buy less compared to previously), but why so for the seller? For instance, suppose each orange was sold for 1 dollar in the past. The price then rose to 2 dollars (reflecting the rise in general price level in the economy) - but if 2 dollars post-inflation is worth the same as 1 dollar before the price rise, then there really is no change in the sellers' purchasing power right? When the seller uses the 2 dollars to buy other things, it will still fetch him the same as 1 dollar did previously!

I'm not sure if I'm missing something here, and would really appreciate some clarification, thank you!

• @keepAlive it's "Economics: Principles & Applications" 6th edition by Robert E. Hall and Marc Lieberman (pg. 580). – Charlz97 Dec 26 '19 at 13:09

If the price of oranges increases from \$1 to \$2, then it does not imply that 2 dollars post-inflation is worth the same as 1 dollar before the price rise; we could expect some devaluation, but it would be proportional to the impact of oranges in the whole economy.
