When did gas prices become the employer's problem?

While surfing the internet today I came across a blog post: High Gas Prices Continue to Cause Employee Pain; Employers are not Offering Help. I thought surely the writer is not going to suggest that it's the employer's responsibility to do something about gas prices. But yes, that's what she was suggesting.

The blogger referenced a survey by the Workforce Institute that basically states the obvious: Higher gas prices mean it's costing workers more to get to work. Consumers have cut spending in other areas of their life to make up the difference.

But where this gets silly, in my opinion, is in reporting that 80% of employees say their employer doesn't provide them any help with higher gas prices. When did the gas prices become the responsibility of the employer? When did it become the company's responsibility to help manage an employee's budget?
