@wjmaggos Free market means a market where prices are adjusted freely due to their natural supply/demand.. In other words, a market where all players are on equal footing.
So that would mean the sort of things intervention is ok for:
1) Stopping monopolies from controlling the market
2) Prevent price fixing of markets by collaborating groups (aggregate monopolies basically)
3) Addressing the fact the medicare by its nature has a broken supply-demand curve, so things that fix that curve.
etc
Now id also be ok with the market spending taxes in general on anything that has a ROI on that money. So for example things like free education, I'd be fine with that because its a wise ROI.
