The biggest money for people controlling the vehicles for communication is advertising. They make their living selling us [X,Y,Z] products / services. If they allow people to know there is serious economic pain, consumers of their products / services retreat and their products / services go unsold. They thus have zero motivation to tell people the truth about economic collapse. The only reason this was somewhat less active under Trump was that they were still able to sell people on "By getting rid of Trump, the economy will get moving again," and thus anticipate further sales in the future. Now that Trump is out, there is once again zero motivation for them to downplay the economy.

All of this is alongside the obvious that the very people promoting the economy are the ones responsible for its performance, thus they don't want to admit responsibility for their role as managers in engineering (partly intentionally, partly unintentionally) the truly historic global collapse that has begun and is accelerating.
