Most millionaires are people close to retirement that own their home. With housing values climbing far faster than inflation, this was something middle class people (working class but making a decent wage, it's not a real class) could do for people who are now nearing retirement. They have approx $1 million, all in the house and a retirement fund.

Newer generations won't even have this, of course. Wages are decreasing relative to core prices, including housing. But that's not something to get pissed at other working class people about. We should channel our anger at the capitalist system.
