Not so long ago, being alive didn't cost much money.
Fruit grew on trees, meat was to be found on wild animals and water just fell from the sky - a gift from nature (or the gods). Houses were found in caves or built from trees, possibly by a parent for a child. Travel was very cheap because we just used our legs, or sat atop an another animal as it moved. When people did things for each other it was out of kindness, or love, or necessity, or possibly to trade favours.
Now, however, for us at least, almost every aspect of life has been successfully monetised by someone, somewhere... and so life is a hell of a lot of expenses.
