I’m pretty sure he was involved with the liberation theology movements in Argentina before the previous pope clamped down on it (in his capacity as a cardinal)

you can model the tax on the supply or the demand. in most simple models the outcome is the same

every dollar you raise, the fewer customers you get. the point is that you should want to raise the price whenever the relative drop in customers is less than the relative increase in price to maximise profits (where marginal cost is marginal benefit :) )

some injustices are structural

right, except sometimes it’s easier to impose conditions on certain countries than others. for example the US was able to get the previous Indian administration to sign a treaty ceding partial control of their arsenal to them, on threat of sanctions (if I recall correctly). as much as the US might want to do something like that with China, it wouldn’t be anywhere near as easy to pull off.

this is just an example, I’m not attaching moral value to what occurred/occurs

can’t you just buy a cheaper USB 3.0 speed cable anyway? or is this a hardware limitation that Apple have put in the port of the phone?

isn’t this supposed to be mitigated by the fact that the tritium eventually blends into the larger ocean such that the concentration remains in harmless levels at the end anyway?
