The owner of a business is not an employee (at least in Austria). Therefore a one man company doesn't pay any wages. The owner just gets the profit that the company makes.
Anyway, it's different in the UK, a company needs a minimum of 2 officers, you can be a sole-trader though. A sole-trader takes drawings from their business account, but it's not necessarily the whole revenue less costs - you might be saving for capital investments and you wouldn't want to pay income tax and Nat.Ins. on that money.
In the UK the owners of a company can be employees too, you can then get money as wages as well as getting dividends as an owner.

You're quite right though, see Ch.2 at https://www.gov.uk/government/uploads/system/uploads/attachm....

Unfortunately I can't add an errata above as editing that post is no longer allowed.
