Very misleading headline. It looks like Mississippi is fighting against banks who are biased in favor of conservatives. Maybe say “Anti-Conservative Bias”
That being said, I agree that this is mainly an issue of corporatist power, enabled by government regulation. State and Federal banking regulation has created so many barriers to entry into the banking business that it is virtually impossible to create any competition for these institutions.
The government bias in favor of consolidating all nature of business into larger and larger institutions (think big pharma, big tech, big finance, big healthcare, etc.) effectively prevents anyone from breaking the institutionalized bias of these organizations, which is uniformly left-leaning. Sadly, the repubs, with their blind faith in “pro-business” policies have paved the way for all of this.
We need to vote for candidates who are pro-economic freedom; but when they get elected, the institutions just buy them off with campaign contributions and fancy dinners and excursions. It is going to be a difficult cycle to break.
All it would take is for the large conservative states like FLorida and Texas to tell these banks that you cannot be chartered in our state (state-level) or simply revoke their FDIC insurance (federal level).
