If one of the fields in a struct is a statically declared array (like the name field in the studentT struct), the parameter gets a copy of the entire array (every bucket value). This is because the complete statically declared array resides within the struct, and the entire struct is copied over as a unit.
2000 Hours is a good estimate for the number of paid hours worked in a year. The per capita GDP is $52,839 (annually), and based on that the average person makes $26.42 per hour. An 8 hour day would get you $211.36 in a day. Keep in mind, however that this is the average income across the entire population.
Each figure is a mean amount, so if wages seem a little high, you can probably blame disproportionally high salaries among each country's wealthiest.

We've also included each nation's minimum wage, courtesy of the Federation of European Employees.
