I'd make it illegal to reject me from jobs I want because 'others had more experience'. In fact, I'd make it illegal to ask or declare how much experience anyone had in doing jobs, to get new blood in.
I'd write off all debt. All of it. I don't care how economists say it would destabilise the world. In fact, fuck it, no more money. No more having to pay for anything, it's all free. It was made up in the first place so IANBU.
All houses are shared out on a lottery system (banded so you get enough space for a family). No more mortgages, jobs, all that shit can go.
Anyone committing a violent act is sent to a man made island of floating rubbish in the middle of the Pacific and left to fend for themselves. This would eradicate both violence and rubbish, so is doubly excellent.
Government is now on a rota system, everyone serves a year. It's simplified down to essential decision making so you don't need 11 month's training either. No wars, so no wasted time on discussion of wars, no money so no stupid discussion about who to fuck with the next budget. Simple.
A cadre of elite scientists to be tasked with finding a way to transport people and goods at faster than light speed, with the promise that they can work when they want, and get lots of thanks (not a job).
I believe my work is done.
