What are the economic forces or math that prevents miners to spam the blockchain?

As a miner they always want to find the block with the most bitcoin. So if fees are high they can get a better return on their investment

So my question is : Can they spam the blockchain with 1sat transactions with 1 sat fee in order to force the market to bid higher ? In the begining they lose money because their 1 sat transactions will get mined but as time goes by market will bid higher and their 1 fee transaction will not get mined because fees are higher now.
