This is wrong. The major sports unions all collectively bargain minimum salaries, and in some cases maximum salaries as well.
I'm not an actor, but on the outside that Catch 22 stinks of Old Boy Network tactics.

And those that don't, want them:

By way of comparison, the rate for a single background-role (i.e., as an extra) in a commercial at SAG rates is more than 3x the non-SAG rate for the same time. ($630 vs $200). If you live in a city like LA or NY, you could make a living wage working (as a background actor) just 45 days a year.
If you cast your mind back to the video game voice actor strike a few years ago, for example, you may recall that one of the justifications for that was that they needed more money because many of them were only getting something like one day's work a month on average. Mostly because no-one outside of the big triple-AAA games could afford to hire union voice actors. Back in the day, a lot of video game and anime voice acting was apparently done by union members under pseudonyms so the union didn't find out; that's probably harder to get away with these days.
This is false. Pretty much every theatrical film, broadcast or cable TV show, and nationally aired commercial in the US is subject to union/guild scales (and even Netflix has begun negotiating with the unions and guilds.)
If you have a "reputation" in Hollywood then you are making above scale because your agent has the leverage to demand above scale. And if you don't, that generally means you are a background player and you're making minimum scale. And at that level, you have trouble finding work because there are hundreds of thousands of other actors competing for the same roles, not because the productions can't afford you.

Yes, because there isn't that much voice over work in video games, and AAA studios were paying minimum scale for games that ultimately grossed hundreds of millions of dollars.

This is false. The union scale for video game voiceover work was $825/session, no residuals no benefits. It usually takes less than 3 sessions to record all of an actor's lines, so you're looking at a total net outlay of less than $2500 for an actor's voiceover work in a video game. If your studio can't afford that for a game in which voiceover work is important enough to justify 3 sessions of recording, then you're not a studio, you're a hobby. (But on that note, a different, lower scale applies to low-budget games, just like it does to low-budget film and TV productions.)
