It's 1000 times better especially when your research is clearly not on the cutting edge and you end up comtemplating life choices because what you're doing are basically useless to the world, and you're only doing it because some funds decided to throw money on it.
At least that's how it is for people whose primary research method is coding, such an easy exit. The powerpoint making variety have it harder though.
I realize this isn't the case for everyone, and I realize my situation was odd, but... there's always a trump card: you can drop out. I get that for international students it's not always so simple (losing your student visa, having to go home) and can be a very hard choice.
My supervisor and my department occasionally tried to push for things that I believed were ridiculous, and the threat of dropping out seemed to work reasonably well to push back on that. My understanding is that a supervisor having a low completion rate is a black mark that can hurt them, especially if they're chasing tenure. I didn't pull this out like a petulant child stomping their feet when they didn't like their chores, but rather when things were getting stupid.
Tony: "This is totally unreasonable and the timeline doesn't work for me."
Supervisor: "This is how it must be. There's no other option."
Tony: "I could drop out and continue on with my life."
Supervisor: "Now wait a minute, let's see what we can do to make this work..."
Normally, during tenure decisions, the grad students and postdocs will be interviewed by the dean. If you work for a pre-tenure prof, and decide to leave, meet with the dean and let them know your concerns before dropping out. Make sure to include lots of physical documentation, such as emails requesting you to do inappropriate things.
I still look back and would have loved to do that research, but I appreciate his honesty.
In Germany PhD is almost always done after an MS and the PhD usually takes 4-6 years depending on the group.
The power your advisors wield over you is terrifying in graduate school. You are severely underpaid AND they have you over a barrel.
