Hmmm... Rich families of Cebu (and other parts of the country)
Ang masulod ra sa akong huna2x are:
1. Spanish collaborators
2. Pre-War American collaborators
3. Japanese collaborators
while most of their fellow Filipinos, or Indios at those times were probably enslaved and oppressed by the Government.
I bet there are also rich families during the Spanish Occupation who supported the rebel Katipunans, but when discovered by the authorities their properties sequestered by the government... therefore removing their names from the history. So kaning mga tawhana mao naa gehapon ni karon, kay nag paling2x rani atong mga panahona.
