The economy ever being "strong" is a lie.
Indeed, if we're talking about normal people and not the ultra-rich. Because when people and economists refer to a 'strong economy,' they're more often than not talking about an economy even more friendly and lucrative than usual for the ultra-rich and the top 1%. They aren't talking about the millions of lower-income and middle-class people. For them, a 'strong economy' only means their employers are raking in even more profits - it doesn't mean that they get paid more or get treated better.
