Engineers are accredited in the US too. But there is an "industrial exemption" that allows you to work as an engineer without a license for certain kinds of employers. You just can't offer engineering services to the public without a license. This is more important in some fields than in others.

Where I work, there are plenty of non licensed engineers, but we pay a 3rd party agency for regulatory approval. The people who work for that agency are licensed engineers. Their expertise is knowing the regulations backwards and forwards.

Here's what I think is happening within industry. More and more work done by people with engineering job titles consists of organizing and arranging things, fitting things together, troubleshooting, dealing with vendors, etc. The reason is the complexity of products. As the number of "things" in a product increases by O(n), the number of relationships increases by O(n^2), so the majority of work has to do with relationships. A small fraction of engineers engages in traditional quantitative engineering. In my observation, the average age of those people is around 60, with a few in their 70s.
