A few things come to my mind on why.

1. We aren’t fresh off of WW2 when a large portion of the planet was personally affected, extremely sensitive and aware of the impact government overreach can cause.
2. We aren’t bored, we have all these highly refined dopamine injecting options, maybe not nefarious in nature but keeps many of us docile and complacent.
3. Extremely effective propaganda to muddy the waters on what’s actually going on and what a united peoples opinion even is.
4. Globalization of the money, I believe on the grand scheme, the money players are softly united behind the scenes and not backing one side or the other but playing the middle ground class war. So no big money to support a cause.
