Most serious traders recognize that "providing liquidity" is a huge joke for the bumpkins. Don't give the banks that kind of credit: even in the best of times, with fractional reserve lending, they are government-sponsored ponzi schemes.

On the other hand, are you sure that silicon valley is driving net material progress? Is Facebook adding or detracting from our material wealth. Would a drug with significant side-effects that swept through the world be a good thing or a bad thing? Are the jobs that are being lost to increasing automation being replaced by better jobs? Or worse ones?

Personally, I am quite ambivalent and confused on these topics, and certainly skeptical of pat answers on either side.
