Conveniently, a few minutes going through public financial statements disproves that outlandish, comical premise.
3M, McDonald's, Wells Fargo, Citigroup, Bank of America, AT&T, Delta, UPS, Disney, Pepsi, Coca Cola, Honeywell, Intel, Walgreens, Goldman Sachs, Walmart, Boeing, Visa, Comcast, Altria, Exxon, Chevron, Nike, Honeywell, Intel, Merck, Pfizer, Cisco, Oracle, Procter & Gamble, Caterpillar, etc.
They're all going to be very upset to discover the 20-35% tax rates they've been paying on their earnings, they could easily have avoided by just squirreling it away in the Caribbean.
One could also do a few minutes of research:
"The average effective tax rate among S&P companies that had posted calendar fourth-quarter results as of Friday was 24.11 percent"

So what US companies tend to do is incorporate subsidiaries in tax friendly locales like the Caribbean (Ireland is also popular) to avoid paying US corporate taxes on this money.
It's quite common.
The question in a discussion of tax avoidance, of course, is 24.11% of what.
The transparency and accountability that Uber brought has been preferred by everyone I know, and people are voting with their dollars.
Before Uber, I already avoided taxis as much as I could, only taking a couple per year.
The notion that people will be kind and nice because of social norms or "plain decency" or something is sentimental hogwash. People behave well when the system rewards them for doing so and penalises them for not.
Then why not just let them compete?
Yes, I pay with credit card 9/10 times and get a receipt. I doubt any of these companies are big enough to have offshore companies to route their income through.
"Then why not just let them compete?"
They do. There's quite big competition in my city among public transport (city owned), many local taxi companies, private taxi drivers and Uber. Competition is quite fierce and costumers can choose freely whatever they prefer. I prefer taxi, I call taxi, some of my friends prefer Uber - they call Uber. What other competition do you have in mind?
You can exercise your opinion by not taking an Uber. Why would you ban a third person from using uber?
The competition you describe is exactly what's needed, but that's not always the competition that's allowed.
