This won't be fixed without a constitutional convention. Either a constitutional convention, or a state-invoked Article V convention would be necessary. Congress won't fix this as it attacks the source of campaign funding.

We need to make several changes to our constitution. These are the most pressing must-implement changes:

1. Only allow the government to provide money to candidates. 2. Get rid of the electoral college for the election of the President and replace it with election by popular vote. 3. Only allow natural persons to get the bill of rights protections. 4. Guarantee the right to vote to all natural or naturalized US citizens 18 years of age or older, and prevent states from implementing obstructions to voting such as voter ID, testing, and permanently barring ex-cons from voting.

These amendments would be nice to have:

1. Establish constitutional controls against rent-seeking and regulatory capture the expense of the free market.

2. Enact banking regulation at the constitutional level.

3. Control lobbying at the constitutional level.

I'm not optimistic about getting these amendments into the constitution. The Federal governement is too powerful, and will probably self-coup to protect its interests.
