This statement is generally true. Areas that were setup as encomiendas ( https://en.wikipedia.org/wiki/Encomienda ) right from the period of Pizzaro and Cortez have retained that exact flavour. Individual strong men rule because that's exactly what was setup. Any "citizen" (ie: indigenous person, slave, or otherwise disenfranchised individual) who tried to go against this system or even escape its clutches was punished severely. It is extremely hard to break that structure. If you wonder why that did not happen in North America, it was because the North was much more sparsely populated and so the colonizers had to setup systems that gave rights to everyone (except of course the sparse indigenous population that needed to be exterminated since it could not be "encomienda"-ed), just so that the companies that sponsored the colonization in North America (like the Virginia company) could turn a profit. It is noteworthy that the Virginia company for example, did actually plan to use the same encomienda approach but was startled to find that there weren't enough compliant indigenous people to enslave. They then switched to trying to strongarm the colonialist/settlers but this had disastrous results. It was only thereafter they gave rights, and privileges to "citizens". This all happened when they became desperate to get a return on their investment.
So yes, your statement is absolutely true. Long tradition indeed. Since 1492 in fact.
