That is because they know that is the only way they can win, and retain power.
And for no more nefarious reason than by retaining power, they retain control over the very system that they’ve been able to plunder, and line their pockets with, for the past 40-50 years.
Plus, by retaining power, they are able to control (with the help of a compliment, lapdaog propoganda fueled media) the narrative, with sources worthy of the Cold War.
Except now, they’re not the good guys.
