Just a few thoughts.
Whilst colonialism by waring nations have steadily decreased across the globe.
(((Or until the next euro-war kicks off)))
Corporate colonialism has steadily increased, seizing power in society, using it's social and economic influence to extract resources; with little or no concern for the worlds fellow inhabitants.
That's because corporate colonial power has no stake, or little compassion for the welfare of indigenous populations or local economy's; over resources.
The super elite are so detached from reality, that they literally live in Alyssum; requiring just a small workforce and an army to realise production or the acquisition of global assets.
Our worlds leaders seemingly avoid all the negative consequences of their complicity in return for there compliance.
The welfare of the surplus population, especially those too young, or too old to work is unprofitable; and as such, is poorly funded, just enough to pacify the masses and stave off civil-unrest.
Globally there is a constant and gradual increase in funding pharmaceutical, mining and military sectors, with the support of the media machine; and a gradual decline in funding environmental schemes, health, and education.

(There may be big trouble ahead)
Nothing has changed for thousands of years.
