I'll use a concrete example of employment services for people who are on welfare. That's a common example. What happens is that companies such as Jobs Now and others tend to accept only people who have been unemployed for less than a certain period of time. They don't take the long-term unemployed as their clients. For example, in British Columbia I think it was that they wouldn't take anyone who had been on welfare for more than six months. However, people who are on welfare long term still need service if you want to get them active in their communities and get them employed. Somebody has to provide that service. But it's not seen as profitable for the private companies, so they don't provide that service.
If you still have the goal, if you want to provide employment services to help people be in their communities and make a living wage, you still have to provide that service. You're almost double-doing it, and the private company is taking the easy cases—they call it cream-skimming. The hard-to-serve cases are left to the public sector. Those are the most expensive cases, so it makes it difficult for the public sector, which has the responsibility to provide service to the most difficult cases.
