The pay depends on the level of Rugby. In the USA the game is amatuer I think so the domestic players are not paid. In the Pro Leagues in Europe for example they are paid less than soccer players with good players getting between 50000 and 100000 pounds a year to play.
Extra money comes from sponsorship and a salary cap paid to international players along with any bonuses from club or country.
They all do (many pay a much higher percentage than the US).
The US plays a game called American Football (often called "Football") that is similar to rugby in many aspects. The Irish have Gaelic Football again it has slight similarities to Rugby
Some other countries participate but the whole world (even the USA) play a similar sport called Rugby.
US Gold medalists make $25,995 per medal. Some other countries pay over 300k for golds.
Countries do accept mail from other countries with foreign postage. In fact, it is the standard practice. If you go to a US Post Office to mail a letter or package to another country, then you will pay in US currency for US postage what the US Post Office charges to send it overseas. Likewise people in other countries pay in their local currency for their national postage to mail things to the US.
the other countries owe weapons from the US
Many products sold in the US are made in other countries, becasue it is cheaper than making them in the US to have them made abroad and pay the cost of transporting them to the US. Howewver, it is not correct to say that most products sold in the US are made abroad.
World War II got the U.S. out of the Great Depression and there was no fighting in the U.S. so the government didn't have to pay for the damage that other countries had to pay for.
Yes, football is only played in the US. Countries in Europe and Asia play a game similar to it called rugby
no Do the people in those other countries want us there?
Depending on specific agreements made between the US and the other country...almost always yes. Just like US Cos pay on profits made in other countries.
the us created the we are the world song and i don't no what other countries did
