Having a child definitely more than doubled my contributions to the GDP.

> Because children don’t contribute to GDP

The simplest model of GDP is productivity per capital times population. And the simplest model in finance is moving cash flows around in time.

Not yet. This is why countries that are not shitholes take care of their children.

Of course they do. Everything a parent buys for a child increases GDP.
