Not sure what you have against minimum wage, it works well in other countries (I’m from the Netherlands). Obviously it doesn’t solve everything by itself, but it’s definitely a valuable part of a range of measures to treat people fairly. It’s a fantasy that everyone can be educated to a level above minimum wage.
It is absolutely fine to mix tabs and spaces in Python, as long as you are consistent about it. It’s not recommended though, as it’s easy to mess up if you’re not paying attention. Most IDE’s will convert tabs to spaces anyway so it’s a bit of a non-issue.
