Online earning opportunities are more in USA when compared to other countries

Um....because they are USA companies looking for USA workers, perhaps...

Most of the opportunities I run across at least for paid surveys are for folks in the US. I think this is probably because like someone else said perhaps they are US companies or regarding products/services that are sold in the US. Seems like laid writing sites are open more inclusively to other countries. Maybe those sites for other countries are out there and we just havent discovered them yet.

There are also a lot in Europe, often geo-targeted to one or two countries. You would even not be able to open several earning sites in my country. It reminds me that I have my daily free lottery ticket to scratch.

I will just accept the fact about this. The most important thing, we can learn from them.
