It's not a question of whether businesses can expand; it is a question of their willingness.

Businesses are stepping up. They're flush, and they're increasingly confident.

Once skittish businesses are turning into confident businesses that are willing and able to hire. I think the job market will improve further in the course of the coming year.

The work force is growing not because employers are hiring a lot of new workers to staff expanding operations. The economy, in other words, is not being driven by businesses out there scouring for opportunity and revenue growth and pushing up wages as they compete to hire more workers.
