Sexually explicit material and prostitution seem to have been part of human society since earliest times, and this suggests some sort of deep seated need rather than evil, surely.

As to the financial aspect, there are many jobs one might wish to avoid, save for financial desire or need - but for some reason the economic coercion argument is largely confined to the sex industry.

Some writers today seem to suggest female empowerment in some types of pornography, and for example Annie Sprinkles (the subject of my own daughter's degree thesis) is sometimes presented as a woman who has taken charge of her own destiny.

I am often suspicious of the Gadarene rush to judgment, and the reaction to the sex industry often seems to me to be one such. The poor conditions sometimes found - coercion, exploitation, and so on - can be found in other economic activities (see, for example the exploitation of migrant workers in the UK, in farming, cockle picking, general labouring, and hospitality, to name but a few areas of endeavour), and are not an issue of the nature of the work, but of the unregulated work practices that arise because, I suggest, the activity is largely covert and therefore unsupervised.
