Where did Richie Rich's family make their money from?

Richie’s dad was “an industrialist”.

^His dad manufactured widgets. Everybody needs a widget. Widgets are used in every machine. Widgets are universal. Everybody loves widgets.

I never realized this was something I needed to know!

I have a wedgie! Er, I mean a widget.

What are the names of Dick and Jane’s parents and what is their father’s occupation?

^^^^ Mom and Dad.

Their parents were “Mother” and “Father.”

Oh yes @Jeruba! Quite right.

They made their money from poor people.
Then they made tax deductible contributions to the community so the poor people would be happy the Rich’s got all their money.
