That was not my experience. I did a PhD in quantum physics in the UK (Imperial College) in 3 years + 6 month extension. I collaborated with Oxford University and I was able to publish in Nature Physics, PRL, etc ... (in other words, the top journals in the field). I was offered post-doc positions but eventually went to industry. I really enjoyed my PhD as a time to learn and think about deep and difficult questions. Regarding employment, I think it shows that you can commit to a problem. It shows perseverance and drive. And those are good skill to have at any technical job.
