Sure, and this 70% of Americans bullshit is propaganda by that measure. It is frequently trotted out on HN and is met with enthusiastic belief despite being total ass pull. There are US Senators pushing this propaganda and people enthusiastically agreeing.
What percentage of Americans do you think live paycheck to paycheck?
Uh, what? People don't "agree" with stats. They either believe it at face value, or they fact check the stats and find, oh, this is actually true but the study was limited, or they find that it is indeed just bullshit. No agreement necessary.
Politicians taking advantage of the fact that their constituents will not fact check them is propaganda 101.
