I initially had issues with basic economy and saw it as a money grab by the airlines. However, I am now a fan of it; traveling has never been cheaper. You book flights from the west coast to europe in BE for the low 300s on a regular basis and domestic flights have definitely reduced in price. While I do agree that the ever shrinking seat is an issue, and if it shrinks even more there will be serious issues flying economy I think the industry is fine as is. There are options that people can get what they want. Personally I rarely check a bag, so why should I pay for a check bag that is built into the price, I also care very little about seat assignment as long as I get from point A to Point B.
I feel like this post while has good points has missed the mark and isn't aware about what BE has done for the price of tickets.
