Not to mention the insane speculation and P/E ratios a lot of these companies have. This is a disaster waiting to happen; something more should have been done after the 2000/2001 bubble burst.
The P/E ratios today are not crazy as it was before 2007-08. P/E ratios always tend to be high in new, maturing industries in a nascent stage or for new technology industries. It is not relevant to a Mfg or FMCG P/E ratio. Secondly, if you talk about companies like Apple or Google & some of the large companies, they are getting massive earnings too. The key here is to redistribute the wealth. That is why there should be a Buffet rule for Large corporations & super high net worth individuals so that they pay atleast 20-25% of profits/income.
The hatred generated for Silicon Valley among the right is ridiculous. There's a large number of good & medium pay jobs that are generated. Most of the leaders are socially progressive & aren't bigots or are lobbying against Climate Change. Bill Gates has donated most of his money to fight poverty. There are obvious problems regarding concentration of wealth but to pretend these people are like the Koch Brothers or Mercers is ridiculous.
And even within the Tech industry there are lot of differences. Bezos & Washington Post rank high in the HP list. The HP level of different organizations vary. You can't lump every organization in a bucket.
