Jim, slavery and serfdom are not an issue in the subject of Robert Owen and social reform in the British industrial revolution.
Slavery was not legal in Britain then or now.

Dave you accuse me of being " happy to tell a lie (everyone believed that etc. etc.)"

It is not a lie. I stand by it.
It was true that it made economic sense to exploit the workers.
Everyone did know that, but some believed exploitation was wrong and a few, the reformers, were prepared to make a sacrifice for what they believed. OK?

You resort to false accusations once again.
You make claims you can not substantiate yet again. Asking you to is no crime.
