I feel sad for those investors but I think we can prevent such scam projects if we invest on a real project with a trusted team.
There is nothing to be sad about. The meme coin lords and senators are very well aware of what they were getting there hands on, there is no point is pitying some one with an eyes but then decide to close his eyes and walk on a high way. What do you think will happen to such person, it's a probability outcome with 70% chance of loosing and 30% chance of losing their capital. A suicide in my opinion, that's what meme coins represent.
If only they have all invested that amount on real project that will slowly develop with future potential., they would have been in mini lambos who knows.

I like the parable you say

and the fact is that it is because there have been so many people who have said that coins with a system like this that rely on pumps and hype and fomo in the end will only lead to misery and this is full of risks if you want to be there.
but indeed it is the choice of those who buy this coin, So, this is the risk in question and there is nothing to regret about this because this is a risk that must be taken.
On the other hand, maybe this will be an experience and a lesson that this kind of thing should not always be used as a livelihood because something like this is a big risk
