What actually is slavery?

Slavery' should be considered in the context of 'money'. When was financial reward invented? When was money invented? The Romans had it, but how much further back can it be traced? Think of 5,000 years ago, even 10,000 years ago. To occupy peoples' time it is quite possible, even probable, that what we would today consider slavery was actually an accepted way of life. A comfortable standard. Basically, kept with housing and food. And activity.

Maintain a potential army in a fit state rather than sit around getting bored. Getting fat. A scenario that may encourage crime. Greed, but in a sense of theft. When did this concept first appear?

Stealing. Ambition: when did these concepts appear?

When were such words as ambition, stealing or theft introduced into modern language?

It is only by looking back from today's 'values' that a very possibly distorted appreciation may be realised.
