No. wrong.
The analogy above would only be correct if all of the following were true:
1) The lamp store in question had one of the most powerful lobbies in Congress, and was therefore the recipient of some of the most shocking largesse from the public trough.
2) There were only a few lamp stores in the world and they used often illegal and certainly immoral means of preventing other lamp stores from opening or gaining market share (see Money For Nothing.)
3) Lamps that cost 3 cents to make were routinely sold for 1000% markup.
Do you think it's wrong to buy the lamp for $15 now? I certainly don't.
