Apps only available in the USA

I am new to Apple and loving it but there's one thing that makes me quite upset to be frank

Why are certain free apps only available in the USA? Infant even some premium apps are only available in the USA...

Had a chat with an old friend of mine over the weekend and I was bragging about all my idevices and in the end he said something I couldn't refute and it left me quite grumpy he said "apple products are only made to satisfy American users" and I couldn't say anything beyond that.

Somebody please wipe the moisture from my ears.....

One more idea, how about all premium apps come with a trial version, even if its a day or a few hours for that matter. one is often forced to purchase an app before they know that all the marketing material was flawed or the app doesn't fulfill what the user is looking for, but the money is gone .....
