Those ideas may sound 'good' but their far from being the silver bullet.

It's amazing that people will take a little snipets from other countries but don't actually account for the full picture. Both Denmark and Australia have xenophobic immigration systems. Not good examples to take from.
Your post is all over the place. Raising minimum wages has an effect on a variety of prices, but that doesn't make it bad thing to do. For one thing, it allows people to spend more on consumer goods, which is good for the economy and brings in more (sales) tax revenue to governments.
No one's saying that high-skill jobs shouldn't still get high wages. That has nothing to do with the minimum wage.
Taxation does require a balanced approach, but that doesn't mean NOT taxing the higher brackets at a higher rate. There are all kinds of ways to tax, not only for the purposes of obtaining revenues but also to encourage or discourage certain types of economic behaviour.
It's a myth that higher taxes stifle motivation – that's been studied to death. Canada used to do this, during the economic golden years of the 50s & 60s (wages were higher then too), and loads of new businesses and innovations happened during that time. That was also the time of low university tuition fees, and students graduated without debt. Not a coincidence.
I don't see what difference it makes whether a major corporation has its head office in Denmark or anywhere else. That literally proves nothing at all.
What do the immigration policies of Denmark and Australia have to do with my comment? My point was that those countries manage their economies very well. I didn't say they were perfect.
And it has to be little snippets. This is an online forum post, not a dissertation.
