732 upvotes made $31,543 two years ago while 1079 upvotes has made only $445 yesterday

A post THE FIRST STEEMIT MAKEUP TUTORIAL- bringing Youtubers to Steemit!! Tara is back! created by Hive account@guerrint 2 years ago which has a total of 732 upvotes made a whopping $31,543

while a post Construyendo el Camino al Éxito - Capítulo 3 created by Hive account@chbartist yesterday which already had 1079 upvotes is worth only $445

I understand it has to do with STEEM POWER of those who upvoted both post, but the gap is too much, does it imply that there were more people with high STEEM POWER years back compared to what we have today?
