Step-by-step explanation:
Basically, individualism is a philosophy that encourages individuals to focus on themselves; working towards attaining only their personal goals, and not that of others, and also not accepting the help of others.
However, collectivism in simple words encourages collective teamwork. In other words, It promotes the philosophy that each individual should work towards archiving the goals of the team, even if it requires putting aside their own personal goals, and also attributing any success they achieve to the whole team, not to themselves.
In terms of general acceptance, collectivism appears to be far more generally encouraged in most societies today, and as such, I agree with the principle behind it.
