Some very simplified answers:

- Everyone would hire more seniors if possible. Juniors are sometimes seen as expensive and hiring only juniors does not scale.

- Education systems do not produce senior people. Also there are other sectors than tech too. I don't know the current situation, but it used to be that places for IT education were never filled completely. There just isn't enough people.

- I don't remember this being reported as significant

- I believe there is difficulties with taxation etc. if you hire people living in different country.
