That the analogy should reference 38 deck chairs instead of 1 is a fine correction.
That the new load of 300 chairs, taken on while sinking, is reduced to 262 new chairs instead of 299, misses the issue: taking on any increased load is stupid, and every leader involved in bickering over the size of the increase should be removed from the decision making process and used as ballast reduction.
Try to pay attention. A deck chair would represent $1 million compared to the "titanic" value of $3.8 trillion, by mass as I estimate. That means it would take 100,000 deck chairs to represent the wrongfully scorned $100 billion, as they amount to 1/38 the mass of the Titanic by the same estimation, and $100 billion is 1/38 of $3.8 trillion.
