Compared to real estate the value of bitcoin is equitable. 

Rich people buy the best real estate which typically maintains or increases its value more that real estate in poorer less or undesirable areas. 

This results in situations where desirable property might increase 20%/annum whereas undesirable property increases by 1%/annum.

 In contrast, all bitcoin increases/decreases at the same rate - the rich don't get to buy better quality more desirable bitcoin.

This is just one way bitcoin is more equitable than fiat. The lack of cantillion effect advantage is another.

And of course, the course appears to claim it's more equitable, not equitable.
