Uber charges different prices to different people. Other companies also engage, or have engaged, in price discrimination. It turns out that identifying customers helps many businesses put customers at a disadvantage.

The only thorough solution is to do what is needed for other reasons: eliminate the systems that let companies know who the customer is.

A new agreement calls for reducing CO2 emissions from ships, but only by 2050, which is far too slow.

The US played a crucial role in blocking a requirement for earlier reductions.

US Ambassador to Vietnam Ted Osius resigned last year rather than ask Vietnam to take back 8,000 refugees that fled after the fall of Saigon.

Most of those people must be pretty old by now. And most of them must have got along badly with the Communist government, which regularly imprisons people that criticize it. If they were back in Vietnam they might be sent to a re-education camp. Probably some of them were in re-education camps before.

The referendum for the UK to leave the EU was marred by massive illegal campaigning by the victorious Leave campaign. Surely this justifies holding another vote.

The EU is itself a kind of business-supremacy treaty. Leaving the EU could enable the UK to throw off some of the EU rules that help business and especially banks dominate all EU countries. But it also presents an easy excuse for yielding to even worse business-supremacy treaties, and that's surely what Tories will do.

US citizens: call on your congresscritter to oppose HR 3144; don't override environmental laws to endanger salmon and the animals that eat them.
