Just as you said the bikes look virtually the same so the cost to manufacture them is low, very low, and so is the technology used, thus the reason for the high profits that Giant makes; Honda's profits are a lot lower but the technology is a lot greater, so if Honda was to sell their MC's at cost that could see a billion dollar profit then Honda wouldn't be selling many motorcycles because they would cost about $80,000 a piece depending on models and options of course, which is why bicycle manufactures can charge a lot because they can get away with and MC manufacturer's cannot and thus the profit margins are lower.
In addition to that 3D printers are now beginning to make bicycle frames which will make them a whole lot cheaper which won't reduce the prices for us it will just increase profits for them.
And there is no need for you to ramble on and on about stuff that isn't pertinent to our discussion which you seem to do a lot of. Mech shifting and tiredness equals elect shifting; cranks with strain gauges, aero wheel speed, 10 speed cassettes being the thing of of the past, all nonsense that has nothing to do with our discussion. I find the 10 speed cass comment odd since Shimano, Sunrace and IRD still make 5, 6 and 7 speed freewheel clusters, so I seriously doubt with all the bikes that have 10 speed cass still on the road that companies will stop making them and the warehouse supplies will just dry up and blow away. Now you have me rambling!
Now on to inflation, something as you say you think you know about me that I know nothing about. Below is a graph of the inflation, apparently the largest inflation period was from 1970 to 1979 at 7.06. Who was the president that started that? Nixon, and do you know what Nixon did to create that situation? I'll let you get back to me on that one because you're the expert and I'm just a flunky. Apparently during Obama's reign it was just 3.22%...BUT, Obama debt caused inflation hasn't caught up with us yet, but it will (and when it does Trump will get the blame), but for our discussion it hasn't yet, thus your argument is a moot point.
