no, you conflated two completely different systems and made a terrible analogy in the process. Are you talking about real life or Monopoly? Either way you're wrong. Interest charges do not reduce the money supply because the banks spend it employing staff, making investments, cleaning the office, lending, paying shareholders, advertising, polishing their golden yachts. For whatever reason, you seem to think the banks destroy all their interest payments. Your entire ideology is based on assertions that are demonstrably wrong.
The banks cover most of their costs by
bank charges. The money supply is
reduced when a loan is repaid. The Interest part further
indebts the real life players of the economy. Whether the interest stays in the economy or not and this is debatable, the interest part increases debt and the money supply
must increase in further loans. If the bank or shareholder keeps the money in the country by purchasing a product of
this country it won’t magically cover interest payments. The interest part the banks charge is usually
reinvested in further fractional reserve banking. Interest is very inflationary and increases the costs of all goods and taxes. So you see the interest part
does reduce the money supply for each player.
You could also have the banker as a player in this game of monopoly. The banker of course does not have to borrow anything and will quickly
monopolize the game. By the time the players go ten or twenty times round the board as the average home loan is he will own every thing,
end of game. You can of course extend the game by allowing more borrowing to be made to the players; if you do not you will have a
Recession or a
Depression
