Did not expect that ending on that post. Oof.
Basically it was a user listing how life changes at different levels of wealth.
ie.
1MM : take family on a big vacation each year
5MM : stop worrying about retirement
10MM : stop working for other people
100MM : private jets to wherever you need to go
and on and on, or something to that effect
Please reply if anyone can find a link.
