) In Icelandic, "win" means "work".
When the poor takes an investment risk of $1000 they risk more than some elite putting up $1000.
What is $1,000 worth to you? Now, that question has a wide range of answers. In some places, that's literally worth multiple lives. Or it could be beyond insignificant.
Obviously very few can or should take a personal investment risk of 100% or more of their net worth.
The original comment was that holding money generates nothing, you have to risk it, and I completely agree. You can risk 20% of your net worth and you're not risking your livelihood, and odds are in ~8 years your investment will have doubled, and your net worth increased by 20%. For some people that's a thousand dollars, others it's ten million. If you want to double your net worth in less than 30 years, you're going to have to risk a lot more. Everyone has access to the same returns on the public market (and we restrict access to private markets for very good reasons).
So it's a literal definition of risk, and as a percentage of net worth it works well. The problem of massive wealth inequality to me is completely adjacent to risking capital in return for investment returns.
