On the other hand owning Google or Facebook shares was a good idea, no?

Be wary of "obvious" things that "should" be true. A lot of people said the Fed was pumping up the stock market with QE, that inflation would go crazy, etc. I ignored them and bought into the market heavily in 2009. Maybe the market is being irrational but I sure did make a lot of money (doubling my personal account and nearly tripling my retirement) by ignoring so called "obvious truths" and investing in a "rigged market".

Maybe in the long term you are right. You sure can lose a lot of money or miss out on a lot of gains that way too.
