New temples.
Screwing bolts, circling nuts, penetrating nails, hardening concrete, accumulating bricks, mixing mortar, grinding stone, polishing granite, melting iron, placing steel, carving wood, mixing cement, spreading plaster, placing glass, cutting aluminum, burying piles, developing foundations, welding boiling, rivets entering, placing lining, layers of paint, gallons of glue, laying electric wire, flexible hoses, miles of tubing, engines running, systems checked, men in hard hats and hard faces, architects drawing, engineers calculating.
Lots of material, lots of people, lots of work; some danger included.
All of these to build an office tower, the new temples of money worship.
