I'm new to effective altruism, but I'll try to explain the connection. As far as I understand, exploring the underlying trends of the labour market and proposing an actionable answer (self-employment, freelancing) is a part of effective altruism, as it can be defined as using "high-quality evidence and careful reasoning to work out how to help others as much as possible".

I'll try to make the connection more clear in future posts! I'm still learning, but I'll get there.
