In order to reduce the illiteracy rate in Spain as soon as possible, Carlo really spared no effort.
On the first day of 1871, Carlo had several royal family-owned newspaper offices publish articles on how education determines income and vigorously promoted the concept of high education leading to high income.
The examples used were simple. The average income of university graduates far exceeded the per capita income of Spain. Particularly, some specially employed university graduates had incomes several times that of ordinary people.
Besides the examples of university graduates, the newspapers also provided examples of ordinary people with elementary and secondary education, whose incomes were higher than those without education after entering factories.
Entering a factory requires the operation of equipment. Educated people often understand the operation procedures of equipment better, adapt faster, and have a lower probability of making mistakes.
