True, but, while those factors may help, they aren't necessary for a country to have visa-free or visa-on-arrival entry to another country. In general, tourism and business travel benefits the destination country, regardless of whether the country of origin is large, small, or a superpower. For most open societies, these forms of temporary immigration are encouraged. What destination countries do not want tend to be the following:

1. People trying to use tourist or business visitor entry permission to circumvent the country's immigration rules. For example, this would include people who intend to stay in the destination country for an extended period or work there. Almost all countries require a visa to immigrate for such purposes and they don't want people trying to circumvent that process.

2. People who can't fund their stay. Whether their intentions are to overstay or not, countries don't want visitors who don't actually have the funds they'll need for their stay and, thus, will be likely to try to draw on social programs of the destination country instead of paying for their own needs. And they certainly don't want people who might resort to crime (theft, etc.) to pay for their needs. Not everyone has a reasonable understanding of what it really costs to visit a certain area, especially in the case of people from low cost-of-living areas visiting high cost-of-living areas.

3. People who may be a security concern for the destination country. For example, countries obviously don't want members of foreign terrorist organizations or foreign spies entering their country.

Mauritius does not have the bargaining power of European Union, it is not a superpower, it does not play an important role in global politics.

Thus, destination countries usually consider what is likely to be ratio of legitimate tourists and business travelers using a visa waiver or visa-on-arrival program to people from the above three categories misusing it when considering whether to grant access to these programs to nationals of a given country. Even if a country is small and not necessarily a large player in global politics, if it's stable, friendly, and has citizens who can generally support themselves and will want to return home after a visit, it's beneficial to a destination country to make it easier for people to visit from that country. It's cheaper for the destination country to process a visa-free or visa-on-arrival entry and it also raises tourism and international trade income, due to people being more likely to visit when it's easier to do so. It's generally a win-win as long as people aren't misusing it.

Wikipedia also has a decent article on the concerns that prompt countries to require visas. In the cases where those concerns are not as large, countries will normally be more willing to grant visa-free or visa-on-arrival entries.
