The quick way to fame and fortune as a journalist is sensationalism and bias
ok, but this is just our cultural karma. say, any musician that seeks fame and fortune must go for canned commercial tunes and videoclips in the fashion of the moment. there's still a lot of musicians that won't get fame or fortune, but produce honest, original and good quality music.
the issue here was cost as in "time is money and if you have to produce 5-6 stories a day, it's just impossible to do them professionaly". a reporter might be sensationalist and even a bit biased and still take the time to do some investigation or fact checking, if he just isn't asked to do so for 5-6 stories a day.
in the end what happens is that there is not enough demand for professional journalism in the market. that's us. we have been trained into to gossip and bias, we want it, it sells, it pacifies ... so why should it change? i guess the last thing that media corporations want is informed and critical reading, so much for informed, critical writing.
at some point it will be even machine generated!
