Not entirely yet, or it would have already entered the political debate. However, in many ways the proliferation (and success) of alternative TLDs indicates that there is an issue. You shouldn't have to use an Indian Ocean domain because .com is squatted to the wazoo.
We have lived through the land-grab era, sooner or later the redistribution era will come.

Considering there are less than a million 4-ascii-letter combinations, obviously not. But there could be more stringent criteria for assignment and revocation, like limits per-company and per-individual, escalating costs in a way that hoarding becomes uneconomical, banning parking (which is absolutely doable, you just need an actual human judge), and so on.
It's the same problem as land. We have more and more people that need it, yet the supply is by definition finite. Hoarding it for yourself not only contributes nothing to the community, it actively prevents others from doing so.
