That is correct. But we're talking here about a very small group of a highly mobile people, not even those with 10m worth of assets, but handful of truly wealthy ones. You simply can't tax them at a country level, it has to be a global system which will never be implemented.
If you step back and look at the last 10-15 years - SM ruling every aspect of our lives, selling lifestyle which has never been achievable for majority and thus making it expected rather than a rare exception. People are generally getting dumber (https://archive.ph/C8rFg) .
The frustration is turning onto neighbours who are just a bit wealthier / doing better, not true global wealth elite. All these talks about tax rises are to tax people who are on what? 100k, 150k? have state pension? people who mostly worked really smart or hard and had some inspiration to achieve. They are taxed to the bone and push them more they'll just drop out of this all together so no more left in the pot to pay for the likes of Weyland.
People who work must be substantially, by very large margin, better off than those out of work. Benefits should be very time limited, to allow to retrain and find another job, but not last for years. Only truly disabled should be supported, but supported generously.
And yes, I do think there is a reasonably sized group in our society, and youth in particular, who'd benefit a lot from being taken from the streets and put in armed service.
