In my country, cheating on the exams, plagiarizing, or getting someone to write your thesis are kind of normal. Imagine trying to remember formulas from your courses, to honestly solve your exam problems, while half of the people in the classroom have their textbooks on their knees and the proctor on the exam pretends he doesn't see. That was how my high-school graduation exam worked. "A mere formality", in the words of one of my teachers.
Now, you would expect this sort of academic dishonesty wouldn't go too far. It turns out that it works at the undergraduate level, too. Only this time, people are more mature, and in a 150 students class, so only 5 don't cheat on the exams, given the opportunity. Then there are the diploma theses. Everyone has to have one, but only 10-15 people go to advisors who are asking them to do actual research. Strangely enough, none of those 10-15 people gets to start a PhD at the university. They just leave the country for a place with a little less corruption.
Getting a PhD in my country follows a few distinct paths. The hard way is to find an advisor who has both a grant and interest for science. The easier ways are to be a professor's relative, or outright bribe a professor, or to be someone with political or financial power. To get the PhD the easy way, you only need a thesis. This is a formality. This is where OP comes in.
Once you have the thesis, the professor makes a thesis committee whose job is to award you the PhD. The committee, and the professor, cost you lots of money. Some professors want just money but there are others who like finer things like art and Japanese cuisine. In any case, this is well worth it. With a PhD you can be a researcher, an assistant professor, or a politician. As a professor, you are so untouchable that you can do things like throw all your students' notebooks over the window and pass the exam only the first ten who bring them back (sorry for not linking this, but I heard it on the bus).
Since the easy way is much easier than the hard way, we have lots of people in the system who just collect salaries. They also have permanent positions in the universities, while the guys who get the grants sit on unpaid "researcher" positions until they get fed up and leave the country.
So back to OP's question, yes, it's definitely wrong, but, if it was my country, the guy would get his thesis written anyway, even if he has to google translate the thesis of someone from Holland. The way to think about things is this: if there are enough people to turn a blind eye to academic dishonesty, soon enough their country would become like mine, i.e. a country whose former prime minister plagiarized his PhD thesis. Or where Italians come to get medical degrees from fake universities. In my country, mobsters, or politicians who happen to be jailed, can also write books in prison, and their term would be reduced. This is a small industry and it was started by another of our prime ministers (the advisor of the one who plagiarized his thesis) who also got jailed for corruption. The way this works, is you ask someone to write the book for you, and, then, there is a university professor to certify the book is scientific. Practically, in every university, there is a professor like that. I could name of the top of my head at least ten famous guys who produced valuable scientific works while in prison, while I barely wrote my own PhD thesis.
In conclusion, if you like how academia works in my country, sure, do the guy's thesis. Maybe you'll end up working for him.
