Looks more like a critique to government spending money on unproductive shit as a measure to "improve the economy". The difference is that you are forced to finance that through taxation, whereas the hole digging is voluntary.
Anyway, judging by the history of CAH Black Friday stunts, I'd say it's definitely a critique of consumerism - of people spending money to buy stupid shit. The difference between CAH and all other Black Friday sales is that CAH tells you up-front you're buying stupid shit (at one occasion, they literally sold bull shit).
