What is the Difference?

In our local paper there was an article about
how a young woman had taken some money
from the employers she worked for. She is
alleged to have taken the money for personal
reasons. So she has been charged with
embezzlement. And she will go to jail for this,
if proven. Which from the article it looks pretty
much given, as she has confess to taking the money.

In New York, and other larger cities, we have employee's
of different titles of CEO's who have taken money from
the company and the US government, used it for hundred
of thousands, for remodel of bathroom (waste basket cost $1,500) and
another redid his office, another gave bonuses to his
fellow employees and etc. This is called "mismanagement
of company funds" and there is no jail time for such things.

I guess the woman in the first one, should have used her employers
money for better health insurance, (as that is why she took the
money) of which would have paid all of her health care in full.
Then maybe it would have been mismanagement of funds also.

Personally, I don't see the difference here of the two examples.
Except the first one was less than $50,000 and the others were
millions to billions. So I guess the more you mismanagement,
the less accountable you be come. And if you use it for something
to make you look good at the job then it is ok too.
