How can a Mcdonalds worker in Denmark make $20 an hour, and yet their Big Mac is still cheaper than it is in the US?

Right wingers always use the BigMac as an example for keeping wages low.
If you raise the wage, everything will have to increase to compensate it, really it didn’t happen in Denmark, or Australia?
Why would it have to happen in the states?
Trickle down economics hasn’t worked for the lower income worker in a great many years, maybe it’s time to try rise up economics, start paying the low income earner a wage they can live off that doesn’t require Government help.
And see what that does for the economy, bet you will be amazed.,
