This is so completely not true. Worked with the Finance Dept heavily at my last job. The accountants keep track of the expenses, and make sure everyone is sticking to the budgets...but the accountants don't make the budgets. Management does. The accountants are the ones making sure that the company can actually pay for everything.
To an accountant, a drop in costs is as valuable to the business as a rise in revenue.
This is also false. To an accountant, a drop in costs is literally the exact opposite of a rise in revenue. (For comparison, it would be like saying that to a software developer having a more powerful computer is the same as writing your software to be more efficient.) A drop in costs is only valuable to the accounting team if there's not enough money to pay for everything, because then the drop in costs makes it possible to pay for more of the bills that the rest of the company incurs. The Finance Dept would absolutely prefer to see more revenue over a drop in costs, because revenue is repeatable and sustainable, while reducing costs is not.
Management are the folks that only cares about the bottom line regardless of how it's reached.
Blame management.
