I was recently applying for a remote job in which the interview committee informed me that as the role is remote, they are recruiting globally. I was then asked for my salary expectations.
I am genuinely confused as to how to answer this question: as this is a position that is hiring globally, it seems that applicants who live in regions where the cost of living is substantially lower can of course in turn list their salary expectations as much lower.
Logically, global-hire positions then seem to me to be a race to the bottom. If I list my salary expectations as the equivalent of $20 an hour, an equally-qualified candidate who lists theirs as $10 an hour will of course logically get the job instead. So what do you do in such a scenario? Offer to work for practically nothing, or risk not getting hired because someone else is willing to work for less?
Furthermore, if someone from cheap country is truly as good as someone from developed country at doing the same job then it is undesirable for them to sell their work too cheaply (let's ignore clickworkers here - we're talking about skilled knowledge work). If quality is there, they want to sell it at marginally lower price. Therefore global competition for skilled work does not necessarily cause race to the bottom - cost of labour will converge to some globally mediocre level long-term. It may go down in the first world, but will go up in cheaper places. Employers are likely to still find it worthwhile to pay more for local candidates work ceteris paribus due to cultural affinity advantage that is difficult to surpass for someone from abroad.
Consider Upwork. There's masses of people spamming the platform with incoherent ramblings about how good they are at doing something real cheap (and still struggling to get enough work), but on the other hand there are people making six figure yearly amounts. That would not be the case if global competition always made the price go down to third world levels.
Just say the amount you feel is fair to ask for what you can do and would the worthwhile for you.
