The Myopic View:
If I can charge my customers more for the same product (or give my customers less for the same old price), then I can make more money.

Also, if I make my labor force "more efficient", I'll need fewer employees, so I'll be able to keep more money.

Yay!  More money!  Go me!


The Macroscopic View:
If all the products cost more (or give less quantity for the same money), people can't afford to buy as much.  

If more people are out of work because all the companies have laid off their employees in the name of increased profit margins, people can't afford to buy anything.

Now no one can afford to buy your overpriced products and you all go out of business.  You're so clever!

But there's always bail-outs!
