I think it is a distraction to focus on the idea that a poor student, parent, or whatever, would not be satisfied if there was a scaling of fees per country and the rhetorical question of where is the fairness in that for them, is also distracting. It is obvious. The whole point of scaling on a country basis is to promote a country's attendance, which promotes the individuals in those countries to the same potential as another country's individuals. That is the goal as opposed to promoting any individual's participation. If the country is given the equal opportunity to attend, then it will have a relatively equal opportunity to support its individuals, from whatever walk of life they may be. The suggestion about students and other low-income individuals is a global problem and out of the scope of country attendance to the event.
The point is not to make it easy for every person! The point is to give everybody a fair chance as though they were all in the same country. If you are a student, parent, whatever... tough luck... that is your focus, choice, circumstance, and position in your country. That determines what your lifestyle is, in a relatively fair manner for your country. If you are rich in your country then relatively speaking you deserve to be rich which means you pay something easier than others in your country.
However, being born into a country sets the standard for every person within that country. This directly affects the success of the international competition through lowering attendance and the selection. This does not need to be a handicap and in attempting to promote an international event, the best way I can see of having solid attendance is to remove such handicaps. A few of you want to insist you are not rich, as though that has any bearing on this... It does not change the fact that you as a low/middle income person will have a much higher chance and ability to attend one of these events than a person of middle income from many other countries. So, by claiming you are low income in your country does not suddenly make a sob story about attending an event which in other countries the equivalent person as yourself does not even fathom considering the possibility.
So, I hope that seperates most of the distractions from the real value of the intended suggestion.
The other point made that suggested people would say it is unfair to have a scaled system, is no different than currently. Do you think people are not already grumbling that it is unfair they have to pay so much? It would just change who is grumbling, but at least it would be a more honorable approach that is being grumbled at. What you are missing is that the system is already scaled, just not in equality.
