To me calling someone seems rude, because the caller demands immediate time from the callee and interrupt them in what they are doing, even if it is only about forcing them to make the decision of picking up, or ignoring the call.
While texting lets the receiver chose when they want to read their message just like the sender when they want to send it. Receivers can still read the message whenever they have some time without missing anything.
"Corporatism vs Capitalism" was invented by capitalists to create a strawman that they can blame instead of blaming capitalism for everything wrong with captitalism.
The rest of the world uses Corporatism for something else entirely, what you might mean is corpocracy or corporate capitalism, which are just manifestations of capitalism.
