"Money" is a concept that is thrown around far too much on Gaia.
Consider: If 90% of all characters on Gaia are independently wealthy to the point where they would be able to live comfortably and then some for the duration of their lives without having to worry about finding a source of income, then that would become the established 'normal' amount of money to have. The poverty line would skyrocket to somewhere around what we see in small business owners (lawl, taverns) or company executives (lawl, O/M). Inflation would run rampant, because since everyone has bottomless pockets the 'value' of money is nearly gone and the price that a person would be expected to pay for a good or service (considering both that only 10% of the population is in the workforce and that those who are fabulously wealthy have all this money to throw around so that they would obviously not be opposed to paying more for something they can't get otherwise [lol, supply and demand]) would shoot straight up by a couple orders of magnitude.
When this happens, Gaian currency won't be worth the paper it's printed on... which is probably why they just give away gold to any schmoe walking down the street.
At this point, the population will be separated into two parts: The working and the unemployed.
Those who fancied themselves to be independently wealthy before do not have an income, do not provide others with a good or service, and may or may not have any marketable skills with which to earn a living. Their 'limitless' funds will quickly dry out due to the vastly increased cost of living, and the money will flow straight into the pockets of the people who are working for a living. The people who work, who own companies, who run establishments, who perform services, etc. or otherwise produce will be the people who have the money, and the ones who relied on their 'deep wallets' will be homeless, penniless, and jobless.
Thusly: The Gaian concept of 'wealthy' can be broken down into two real groups. Those who have enough money to live on because they spend it wisely, and those who have an impressive income because they provide goods or services that others require. In the first category, we would stick someone like Flare who just 'has money'. In the second, we would stick someone like Mr. Brown who runs a well-operated company that provides something not many businesses in Gaia do.
The status quo is preserved. Capitalism wins.
