It’s always been a hard problem to solve, and the bankers who solved it always got paid handsomely for enabling commerce.

In the old days everyone bartered. Then came shells. Then precious metals. The gold had to be literally shipped around. Everyone from the Roman to the British empire had to physically ship chests of gold to it’s soldiers. Cross border commerce was absolutely fraught with risk. Piracy and shipwrecks galore.

Then the Rothschilds opened the first international bank, dramatically cutting the difficulty and expense of international trade.

We got cheques, paper money, and the credit card control room you worked in.

At every step, it got faster, cheaper, safer, more ephemeral. Trade increased dramatically. It’s amazing! The much-maligned banking sector is really a triumph of capitalism.
