I am individualist.
Can you explain what Eastern countries have collectivist settings by the way?
Japan? Not really, your 'individualism' is very present there in the form of 'honor', which is an inherently self interested abstraction.
China? Nope, again, the top end of society tend to move and act as freely as normal.
Singapore (Extremely rich country). Well they are very individualist, but also very patriotic, is patriotism a form of collectivism? If so, why is it incompatible with Modern capitalism?
Dubai? Nope, they have a royal family.
Care to name any others? Virtually every successful Eastern and Western country has individualist philosophy at its core, and why not? The tyranny of the majority is an incredibly scary thing, the rule of Pal Pott and Mao where intellectuals, hell even people who wore glasses, were lynch mobbed because of their percieved superiority/threat to the uneducated mass.
Individualism is a fundamental part of human beings, we only know ourselves truly, nobody else does. So it makes sense for those capabilities to not be limited by other people. When I win a race, I win it for myself and for the people I want to win it for (The people who support me), I do not win it for society, I do not win it for some abstract 'good'.
