while long term changes to banking would be a huge help shits so bad right now they need to implement rapid changes that will be seen within a couple of years aswell. a quick easy one for the us is a national program to repair / rebuild all the infrastructure like bridges and dams that were built in the 50s and have continuously had maintenance budget cuts since. run this alongside subsidized training for the work (excavator / crane licences ect.) and pay well putting upwards pressure on the private job market. if the government is offering free training and $35/h suddenly anyone with a shit job is leaving and wages have to increase to get people in. this is what fdr and hitler did with interstates and hoover did with the dam, it's proven to work.
