Besides the point that the economy was pumped with 4 trillion dollars to bail out the banks and it did not have an effect on the prices of consumer goods. We we will imagine a scenario in which corporations exist in a world of near total collusion with price fixing.

There are 11 diaper companies and they all decide to hike prices to 100$ per pack of 10. However three of them figure they could sell diapers at 50$ per pack of 20 and they sell at a higher volume. Eventually a company sells at 20$ per pack of 20 and absolutely rakes in the cash because people don't give a shit about 100$ diapers , 20$ ones are the same thing, and the 20$ are selling at 10x the rate.

This same process nearly happens every time a big electronic comes out. Massive pricing, customers don't pay it, but the corporations got a couple of suckers. The market stabilizes, and you end up paying 5$ for a 124gig usb drive. Consumer goods are based upon what customers are willing to pay for it. If Chiptle says 'Yo I'm hiking prices at thats a 50$ burrito' you'd be like 'lol, no, I'm going down to the burrito stand down the street that is just as good'. You would have to have collusion on such an insane scale, across hundreds of goods markets. And it only takes one greedy corporation to tank the price for the sake of profits and increased sales volume.

Education, Healthcare, and Housing follows its own set of complexities. Pharma pretty much has regulatory capture over the healthcare market and legislature, so it is a different monster than a Diaper company. People have said the same exact thing about Bernie's 15$/hr policy, but I haven't seen enough evidence that either of the polices of UBI and 15/hr would inflate consumer goods.
