Real Madrid has not always been like this. There were times when Real Madrid was not a very rich club and neither a very strong one. But they have reached there with some good decisions and some very good performance.
Oh no? When?
I don't know if you mean 1902, which is when it was founded, but at that time no club was rich. Football didn't move as much money as it does today.
If we take into account that it is the biggest club in the capital of Spain, where all the political and financial power is concentrated, and that there was a dictator in Spain between 1939 and 1975 whose favourite club was Real Madrid, either you support what you say with some data or I will believe that you have said the first nonsense that has crossed your mind about it.
