When interest rates are low and/or stocks are overvalued, interest in alternative asset classes like venture is supposed to increase. Think of it like a BATNA in negotiations.
Right, so what are possible explanations for interest in alternative asset classes not increasing, and why is that worrisome?
I'm not sure it's worrisome but putting your money in asset classes with low appreciation potential is still an improvement over setting it on fire.
I think it's worrisome because it means people are keeping their money in stocks - they aren't acting as if the market as overvalued, even when everyone's talking about it (which could contribute to a bubble pop).
