Hi @pitboy, you are a new user here and the question you are asking yourself is more than legitimate.
I will try to give you my vision of the facts.
First of all, not everyone likes the same content and this was predictable, also the fact that you are a new user and nobody knows you.

Now let's move on to the real reasons why shitty posts earn more than better posts.

1 * many whales only vote for visibility, don't hope for some of these votes.

2 * many whales vote for curation, therefore obtaining a reward from the vote they give, this implies the non-interest in the quality, but exclusively in the return that they can have

3* the distribution of power, and by power I mean care trails, proxies and delegate, is in the hands of a few users who can decide to move large quantities of voting at one time, if you do not fall within their friendships, do not hope to receive these votes.
