Yair . . . John C.. It's an interesting conundrum. These are the issues that I find interesting.
Without venturing into the questionable territory of politics I have long thought that income derived by any individual or business, doing useful work be it a mechanic repairing equipment, a truck driver delivering goods, a doctor consulting patients, a solicitor writing briefs and so on should be relatively lowly taxed and "unearned" income such as loaning money (often at ursurous interest rates), stock market speculation, real estate speculation should provide the bulk of the taxation pool to run our countries.
In other words an incentive for folks to work and employ people to actually do and make and produce tangible things. It probably sounds naïve and simplistic but our present system seems to need an upgrade.
A bit O/T on your thread about automation but I am sure you get my drift.
Cheers.
