Tesla does the fair thing that any company should do which is determine the price based on a fair margin and charge everyone worldwide accordingly.
"Laws" of economics, be damned then, right?
I put laws in quotes because, of course, they aren't really absolute truths like Laws of physics, but that's how they word it in University, so I stick with it.
The general macroeconomic principles of the "invisible hand" - or supply and demand - don't generally allow for "fair", or what you perceive as fair. I fully disagree that it is fair, btw. Well, "fair" to Tesla, I suppose. But "fair" is subjective and not really relevant to what "is".
I said it before. You don't care if a baker's cost of wheat goes up or down, right? If he charges "too much" for his bread - particularly if you have options - you don't buy it. You don't listen to his whining about wheat and then buy it anyway. OK, maybe you do, but macroeconomics isn't about "you" (or me), but about the market as a whole. Tesla's costs are completely irrelevant to its pricing from the customer's point of view. It may matter to TSLA investors, but not Tesla customers. Except in craft fairs and commodities, input costs have nothing to do with pricing outside of the company's willingness to offer the product (supply). If they can't make a profit at the price the demand will allow due to their costs then they don't sell (supply goes down which allows for a higher price to a smaller demand base).
Ultimately, I believe, Tesla is making a mistake with its pricing outside of the USA, but only insomuch as they CARE about the long term viability in those markets, which maybe they just don't.
Anyway, I've made my case. We don't need to keep going round and round.
