Wikidefinition of "An Economy"

I see they have changed the definition of an "economy" on wikipedia!

Very interesting.

Here is the new wikidefinition:
"An economy is the ways in which people use their environment to meet their material needs."

I feel quite vindicated by this change in definition.

I feel vindicated because if you really think about this definition you will realise there is no such thing as "an economy."

Even if this definition were accepted it can plainly be seen from it that economics is politics - id est "the ways in which people use the environment to meet their needs" is surely determined entirely by politics.

Tell me if I am wrong.
