> 1. Why should harming a million people identically reduce their right to a fair legal evaluation and possibly compensation for damages?

It doesn’t. You can almost[1] always opt out of class action lawsuits to pursue your own suit. This would be expensive and unwise for most people, but you have right.

[1] There are rare exceptions.

No, because the limitation is not money. More money does not magically make the humans in the profession be able to handle higher case-loads, nor magically produce new lawyers and judges. The bottleneck is time that each case takes to be properly and thoroughly adjudicated, and neither "more money" nor "more people" can accelerate that. While it's certainly correct to say that more staff could handle a larger number of cases, a. more staff = more cases, but more money doesn't speed up those cases, so there's still not really anything to be gained in terms of efficiency by increasing individual case costs. And b. if the solution was as simple as "hire more judges", it would have happened already.

Courts aren't lacking in budget to hire more people. They're lacking in people available to hire, with the specific expertise that they need to fill any gaps. The legal profession, at least in the US, consistently has some of the lowest unemployment rates across the board. Unlike over here in the tech sector, the scarcity is in available talent, rather than available jobs.
