Well, that is what happens with a positive time preference. Being wealthy today is better than being wealthy tomorrow.

If you were to sit down and think about how war creates wealth you would at first think that it can't because it costs money to go to war and pillaging ruins the source of the spoils.

However, the urgency of money (interest on debt) creates a desire to have it earlier than later. If you can pay your debts back sooner you avoid paying interest. Therefore it is in your best interest to overharvest your farms, overfish the waters, overgraze the field, exploit your workers and pillage the village. Of course, the same applies to the lender. He wants to earn as much money as possible so he must obtain it as early as possible so that his interest compounds.

Of course in practice inflation puts a damper on that form of extortion and causes the time preference to shift negative. If your money is losing 50% of its value in 20 years you'd accumulate as little as possible and would rather receive money in the future because the amount of value you produce hasn't decreased which means you get twice as much coin in the future to represent the same amount of value.
