Ah yes, by buying my dinner with my money I, not their fucking boss, am taking money out of their pockets.

You see, this is the problem. You think solidarity is just a ticket to unbounded gains, so you encourage a pattern of behaviours that only contribute to the downward spiral. You’re not ready for solidarity, yet. You need to start with trust. If you don’t think your clients should be able to expect you to set prices that cover the cost of the exchanged goods and services, that they should instead guilt splurge so that your notoriously wage stealing boss, then you aren’t in a position to be serious about contributing to a movement of solidarity.
