I don't believe these people should be marginalised to menial or tedious jobs with little appreciation and a pittance as pay. Essentially to render them invisible to the larger operation of society. This might be hopelessly naïve on my part, but I believe they can be just as productive in a different capacity.

Trade schools and apprenticeships can greatly reduce the burden society must endure in order to level the field for non-skilled labour. I don't believe white and blue colour jobs need such a strong line dividing them and so I'm sure new avenues for selling services or exchanging things of value and different definitions of what we value will emerge.

Of course, this is now getting into an area outside the scope of - and much complicated than - a robot parking system ;-)
