A Worry in Financial Industry

I am in Financial industry in Tycoon.
Financial industry is the one of the most profitable industry.
I start feeling worry whether how long can financial industry stands on the top?

If we look at the price of all the upkeep,
the price is increasing.
Inflation is happening.

If inflation continuing to be happened for a long time,
financial industry will be hurt the most.

Unlikely other industry,
financial industry's upkeep cost is raising while the revenue couldn't.
We take utilities industry as comparison.
Petroluem Power Plant produces power while its upkeep is petroleum.
The petroleum price might raise which lead to the increase in the cost.
However, the price of power might raise to which increase its profit back.

But this won't happen to financial industry revenue which is money.
The value of money wouldn't increase.
In fact,
its value will drop due to the inflation.
