It depends on what your definition of common folks is. Even here in Montreal, where housing prices have been historically depressed VS the US and the rest of Canada, I know plenty of families with very modest salaries who bought 200-300k $ homes 10-20 years ago that are now worth well north of 1.5m+. Obviously a lot of people didn't get richer, but a huge proportion of the population did (at least on paper).

By any definition being worth more than 1m$ is a lot of money, especially here. But it seems like the goalposts keep getting moved to the point where saying "what about the millionaires" is seen as an attack on the working class because billionaires exist. I've seen people argue that Bernie wasn't rich because he is just worth less than 2m$(!!). Sure, billionaires have a lot more wealth than your average millionaire but I'd bet even taxing them at 100% would bring so much less revenue than raising the tax rates on the "lower millionaire bourgeoisie" by a few percentage points. Yes we can do both, but it's not going to happen considering the complete focus on the mega wealthy sometimes coming from other rich people in denial.
