Democrats are already all over this, and they are the ones planning on holding a hearing and bringing Robinhood to the hearing. Biden has other pressing issues, like fixing the smoking wreckage left behind from the last guy.
The Democrats aren't going to do shit...for the same reason the Republicans didn't do shit.
They are bought and paid for.
Let me paint you the picture...
Republicans for years were the beneficiaries of Wall Street and corporate cash.
They protected Wall Street.
The left complained about this arraignment. The right defended it.
Bush Jr comes and goes, bailing out Wall Street on his way out the door...
This triggers a shift in the Republican Party constituency...not the leader ship...the rank and file.
"Too Big to Fail" , "We had to destroy Capitalism in order to save it", "America will becomea service economy" and corporations off-shoring manufacturing (off-shoring...a euphemism for betraying American workers and moving to countries with obscenely cheap labor while continue to sell the majority of those products here, extracting our wealth were contributing nothing)...these were just too big of pills to swallow
The rank and file began to make a populist turn.
