I'm sure shale has lost money for some Wall Street investors during the last 10-15 years, but I'd say that in the great scheme of things the newly-acquired resilience provided to the US economy and especially to the US consumers by the US not having to fight wars in the Middle East in order to get its oil has a been a net benefit to the US economy, and hence to Wall Street as a whole. That is those Wall Street investors took one for the team.

Ditto for the current geo-political thing where European companies are actively divesting from their home-markets and investing instead in the US, partly because energy (including natural gas) is cheaper in the United States.
