The middle panel up top has baggage. Maybe it goes without saying, but even people with sizeable investments profit or exist at the whims of capitalism. More than 1 ghoulish landlord lost most of their hoarded wealth during the housing crisis, and plenty of "small business" owners can see themselves muscled out if larger capitalist set their eyes on a market and bribing (buying out) is off the table. Every petite bourgeoisie is always one manufactured capitalist crisis away from losing their artificially granted "class".

They will probably not come around but it's worth reminding them to take the wind out of their sails. Maybe they'll be materially worse off under a Marxist system right now, but there is value in living in a society where you will not be abandoned by society or go hungry, nor have to see others suffer that way.

I went off topic but I think that "no other investments" line is too open to wrong interpretations.
