Others (including myself) focus on the money. Is the money being used efficiently for things the population wants? How can people more efficiently allocate money so that we all benefit. After all, if the money is being used to its maximum effectiveness, shouldn't all the people benefit? Let's look at the money, decide how efficiently we can get that to move around, then the people will follow along behind that.
Capital gains is where this difference in philosophy hits hardest. Do we want rich folks paying the same as wage earners? Or do we want people who are better at allocating money to things that advance the species in general to have more ability to do more of that?
There's no right or wrong answer. People on both sides take the arguments too far. But when you have no entrepreneurial community and the few that you have are publicly screaming at you to slack off, perhaps you've gone a little too far in one direction.
My question is "How do governments learn what is a happy medium?" I think the answer is regularly changing up who is in charge, because there is no exact and unchanging answer. Here's hoping the French will have a chance to adjust before they destroy what little is left of their startup economy.
I'd also note that laws and policy many times are made based on the public's caricatured idea of something instead of the thing that actually exists. In the U.S., it's common to hear politicians rail against "big corporations" while proposing policies that would sack the local stock broker or web startup guy. Meanwhile the truly large corporations have lawyered up and done enough regulatory capture that they skate through. There can be a huge difference between what's advertised and what the public actually gets.
