About firing fast and easy, it is a bad idea.
I work in Sweden. I don't think I have seen ever anyone fired. What I have seen is some of the best hiring processes. The process looks at the candidate values, and skills. And there is a discussion about what we expect from her, and what she expects from the job.
I worked previously in Spain, I saw a lot of people fired for no good reason. And they were also hired without too much attention. Shorts interviews, no real testing, are part of a process that ends consuming a lot of effort from everyone after hiring someone that is not the correct person. Other times that people is good, and leaves, because was not the job for them.
Both seem related. Cheap and easy firing produces careless recruiting. And that is more expensive that people realizes.
