redistribution of wealth.
In practice this would mean that all jobs would pay RSUs of some kind. If you rent then you are getting some of the equity of the house as well, so that when it is sold you benefit and not just the landlord.
The idea is basically that everyone should benefit from capitalism, not the just the lucky few with all the capital.
Note the 'almost'. I'm sure some outliers exist but that's not what we're talking about.
You get charged interest. Then, you might have your wages garnished. If that isn't sufficient, your bank accounts might get frozen. If that still isn't sufficient, liens.
