I don’t get it. Even publicly traded companies try to zero out end of year profits via reinvestment and salary bonuses. If you did not then you accumulate unused cash which if you decide to pay out to employees later gets double taxed.

But in any case Uber’s industries are still highly competitive (ride sharing and food delivery), so there are plenty of ways for them to reinvest profits rather than accumulate a war chest like a company like Apple (which also was able to do partly because of a tax haven country).

Plus if Uber didn’t reinvest profits their hundreds of competitors would do that and get an edge, many of which are smaller private startups
