One theory I've heard about the accelerating of the worsening conditions of western proletariat is that the USSR used to provide a bulwark against things getting too bad. People would point at the USSR and the illusion that capitalism was better for individual prosperity would collapse in comparison. Then, with the USSR gone things have been deteriorating for the past ~30 years.
If that is true, even somewhat, why haven't we seen a similar effect from China's example? Is the theory simply wrong? Maybe western capitalism is just unable to even offer scraps from the table at this point. Maybe people are unaware of how things are in China? Could we dare to expect that China's example will force a lifting of the boot from our necks?
I think a few reasons. First they can't afford it, second they're pinned by various influential lobbies (e.g. fossil fuels opposing green energy), and third they have a much more powerful media sector now and any enviable news that comes out of China is overwhelmingly disbelieved if mentioned at all.
