All intentional. But the wealth destruction is only happening to us normie plebs (better known as "trickle up economics"), the top 1% are loving this and getter richer with every bomb that is dropped, every building that is destroyed, and with every gallon of gasoline that is being pumped.
George Orwell's Nineteen Eighty-four:
"The war is not meant to be won. It is meant to be continuous. The essential act of modern warfare is the destruction of the produce of human labour. A hierarchical society is only possible on the basis of poverty and ignorance. In principle, the war effort is always planned to keep society on the brink of starvation. The war is waged by the ruling group against its own subjects, and its object is not victory over Eurasia or Eastasia, but to keep the very structure of society intact.
"The problem was how to keep the wheels of industry turning without increasing the real wealth of the world. Goods must be produced, but they must not be distributed. And in practice the only way of achieving this was by continuous warfare.
"The essential act of war is destruction, not necessarily of human lives, but of the products of human labour. War is a way of shattering to pieces, or pouring into the stratosphere, or sinking in the depths of the sea, materials which might otherwise be used to make the masses too comfortable, and hence, in the long run, too intelligent.
"Even when weapons of war are not actually destroyed, their manufacture is still a convenient way of expending labour power without producing anything that can be consumed. A Floating Fortress, for example, has locked up in it the labour that would build several hundred cargo-ships."
