big no no

I don't understand one thing. How do people get good, well-paid jobs in media, where they're required to write a lot, when they can't use the language correctly? I'm talking about the Swedish language right now, but it obviously goes for all languages. I know that I'm a language geek and I really can't stand obvious mistakes, even though I'm sure I make them myself every now and then, although definitely not as much in Swedish as in English. Certain words are just so basic, even a fifth grader should know how to use them correctly, yet I just spotted a very serious abuse of the Swedish language by a media person who misspelled this particular word. In Swedish, words should generally not be separated, fifth grader for example would in Swedish be fifthgrader. And I realize that everyone can make mistakes, it happens, but writing jätte mycket, which basically means a lot, something that you use quite a bit, is just unforgivable in my eyes. I guess it's pretty much the same as writing alot, which also seems to be a frequent mistake. Especially an educated person who writes for a living should not be able to make a mistake like that, it should be physically impossible to hit the space key between the two (inseperable) words.

All I want to know is, if people like that could get jobs in media, then why couldn't I?
