One of the reasons, vocational training works well in Germany is that they have a long history of doing it, stretching back to medieval guilds.
Germans (maybe as a result, maybe because that’s just how Germans think) also have a real thing for ‘doing things properly’. That way may actually be rubbish but if it is the way they think a job should be done, that is how they will want to do it.
Trying to import that sort of system into countries which either never had it (the US pretty much) or ruthlessly disposed of it (the UK pretty much) is not surprisingly hard because all the various cultural background things that prop up the system aren’t there.
So you end up with (for example) employers who think “Why should I train my staff properly? They’ll just sod off and work somewhere else.”
Or ‘training companies’ who just exist to take people’s money without providing any actual useful training.
Or ‘training companies’ which exist mainly to keep people off the unemployment statistics (a UK specialty).
