Many German expressions having to do with money are very similar to those in English, in fact the expressions may have been derived from and adapted by one or the other of the two languages. Some examples are: Geld waschen (to launder money), Das Geld zum Fenster hinauswerfen (to throw money out the window) and nach Geld stinken (to be filthy rich). Some expressions are not quite so direct, however, such as: Geld regiert die Welt (money makes the world go round, literally "money rules the world"), Im Geld schwimmen (to roll in money, literally "to swim in money"), and Das Geld liegt nicht auf der Straße (money doesn't grow on trees, literally "money doesn't lie on the street"). Here are some more examples from Yabla videos:
This one is pretty obvious:
Zeit ist Geld und Geld ist gut
Time is money and money is good

See if you can understand the correct English meanings for the following German money-related expressions without resorting to a search engine or online dictionary by just using the vocabulary you already have: Geld allein macht nicht glücklich; Wer den Pfennig nicht ehrt, ist des Talers nicht wert (a hint on this one: a Taler is an old-fashioned currency like the dollar or euro); Sie haben Geld wie Heu; Es geht nur ums Geld; and last of all, the most difficult one: Unrecht Gut gedeihet nicht.
