While you can't say for sure that Android users have less money, you can say they're spending less money on their phones which likely means they'll spend less on apps on that phone.
Also, as Android has a higher footprint in Asia, making games that resonate with the Japanese/Korean audience is pretty important, and I'm not sure if Monument Valley qualifies.
While that's true, that's no different from PC games and they still make considerably more than android games do. There's definitely an X factor here.
At the other hand iTunes cards are basically everywhere.
Because that's how you fight piracy - making possible that people can buy your shit easier in the first place.
If the success or failure of your software marketplace comes down to a lack of gift cards, you have some serious problems.
Same thing with movie/music/TV piracy:
- either services aren't available,
- they are but the selection is gimped in dragonland thanks to licenses,
- and or again the only way to purchase subscription is with a CC.
You could say that each Google Play customer is punching above their weight, but GooglePlay+Amazon+AmazonUnderground+iDreamSky technically means that Android makes up 58% of the customers and only about 1/4 of the revenue compared to iOS.

To be honest, I usually expect my Android apps to be free, and there's huge friction for paying for anything because Google doesn't support standard payment methods in my country (heck, in my continent, South America), they keep expecting international credit cards which almost no-one has.
There's also an electronic transfer system managed by the ATM company called Banred.
In Brazil, the most common system is "Boleto Bancario".

I understand that my country is tiny and no sane company would implement payment systems for us, but the use of Boleto would probably increase the Android app market by a lot, currently people use hacks like buying gift cards through the eBay equivalent with Boleto, but it obviously implies a lot of friction:

There's an interesting lesson in that a local company called wOOw beat Groupon head-to-head in the deals market simply by enabling the popular payment methods, while Groupon was unable to adapt to the local conditions and kept asking for credit cards. Groupon ended up closing in Uruguay.
