If you sell to modern scum, you must sell what modern scum want. Modern scum hate everything that is good, everything that has value. Don't believe me? I couldn't get modern scum to use a free service that doubles their income. Modern scum only want useless crap, nothing else. How do you figure out what useless crap modern scum want? You must either be in tune with modern scum or have connections to modern scum to give you ideas. I have neither of these.
So what are the options for someone like me? One option is to enter an existing market where there is proven demand. You will have to compete with other businesses for market share, and try to win with better execution. I am trying this. The other option is to try to do business with people who aren't modern scum. This means the Japanese or traditional Anabaptists. To the best of my knowledge, the rest of humanity is modern scum. I haven't tried this option, but I believe it is worth trying and I hope someone does and tells me how it worked out.
