(Not suggesting that you're not competent, of course, but I don't think you're and economist and neither am I.)
The closest I get to being a competent economist is some familiarity with Canadian prosperity when we had some of those measures in effect, looking at some of the nations that report a high level of citizen satisfaction, and reading John Kenneth Galbraith.
I don't see how letting people off crippling debt would harm the nation. Though it would certainly make a lot of bankers cry into their Chivas and put cesspool scum like Payday Loans and the the guy who buys your grandmother's jewelry for peanuts out of business, it would also free up a huge amount of capital for small independent startups and put some homeless people under shelter. As for providing a single, universal basic income, think of all the welfare agencies consolidated into a single, streamlined, well organized operation. (with some concomitant loss of employmen) Then, add the savings from all the people who would not be arrested, tried and jailed for petty crimes of desperation, and illness caused by malnutrition, exposure and sanxiety.
Collecting all the government health schemes like Medicare, Medicaid, VAC and ACA under a single administration and expand it to all health coverage, charging a variable rate according to income, withheld by the employer. That would not only not only liberate funds from profit to be used in the actual health care system, but also cut a lot of redundant office jobs (I'm coming to that) and render a lot of office space available for new businesses to rent.
As for the student loans, making them available to qualified students at 5% flat rate, would not be a loss to the government - they would still get more money back, from a healthy labour force of grateful graduates.
Some bank employees might become redundant, along with the other unnecessary paper-pushers, but they could all get cheap loans to retrain in building trades, social work, health support, childcare, solar and wind generation, water purification, land reclamation, installing hydroponic farms in disused office towers, and all those startups looking to hire skilled workers. Some could even go on doing clerical work.
In case any of my proposed reforms did cost the government money, or subtract from the nation's general wealth (keeping in mind that the megarich often don't reinvest their profits on domestic improvements, but use them to buy destructive propaganda and politicians), it would be more than offset by the extra revenues. If it's still not enough revenu, forget about trying to control guns through legislation - just slap a 5000% sales tax on ammunition.
