The first verse of the song Take Back The Instant by General Elektriks is the following:
Take back the instant
When you brushed him off your shirt
You tried to drag him to the trash
You tried to trade him in for cash
The lyrics as I understand them are about distribution of wealth, and how some people are born lucky and grow up to take everything for granted. The first verse is in line with that, but I don't understand the last line: what does trade somebody in mean?
My first thought was that it was a similar construct as "show somebody in", and so it meant invite somebody into a deal. Could the line be rewritten as "You tried to make a deal with him to extort his money"?
