Being a Steemit Person but mostly just like Posts, Videos e.t.c.

I dont know if that is a Problem but i feel like there are a lot of People on Steemit that just look and do not really post anything and mostly like stuff.

And as i understand they will not get any Steem from it nor give any Steem.

I can understand some part of why it is like that but i think its harder to expand the Community or am i thinking wrong?
