I have pointed out a couple known and realistic examples why wages in one country doesn’t imply they’ll work in another, under the umbrella of a single corporation.
As you say, making that implication as OP and you did is spreading a claim Without doing any work to justify that claim.
That work needed is financial statement analysis, starting with breaking open a 10K. It’s not my job to do that, as you’re the pair that made the implication in the first place.
I’m pointing out that by you not doing the work to justify the claim, there are numerous straight forward financial accounting reasons for why the claim could be wrong.
If you don’t know much FSA, that’s fine, but from that knowledge base you should know that you’re basically saying it could rain purple and it’s my job to use standard weather data to disprove why that’s not the likely answer.
So as far as I can tell, you are just trying to spread doubt without doing any work to justify that doubt.
IMHO fast food is a durable industry and while prices/locations/hours may change, it seems absolutely ridiculous to argue that there isn't a business model that will be profitable.
