Exxon is doing great and will continue to do great. There is no data to support your assertion that the government is trying to kill them. There is strong demand for oil and gas for the foreseeable future. Most big oil and gas companies have revised their forecasts based on reality and we are getting ready to see a big wave of exploratory and drilling activity.
Yes, electrification is coming, but as a reference, the last coal locomotives in the US were retired in the 1980s. Oil and gas has decades of great times ahead of them. Most of those power plants that provide the electricity for electrification are currently powered by gas.
Do you really think Exxon cares about their carbon footprint? Do you really think they care about their ESG score? Yep. They sure do to the point that by paying at least lip service to both gets them more and better customers and allows them to make money. That's it. That's why it exists. Same at every big US corporation.

Back to the original subject, SWA isnt BB&B. Not even close. They make money despite their inability to get out of their own way. That will continue as long as there is an oligopoly in US air travel. BB&B was struggling to find market share in an ever broadening environment of competition and refused to change. I went in one of their stores recently. Great stuff, but wow was it expensive. You can literally walk around with the Amazon app and shop their showroom by scanning upc codes and get it (or very similar products) delivered to your house at a huge discount.
