I assume you meant the top 10%. In the US 56% of people will spend a year or more in the top 10%. 12% of people will spend a year or more in the top 1%.
The 1% for the most part aren't billionaires. Last year in the US, the threshold was just under $285,000. Ignoring professionals, plenty of small business owners can hit that on a lucky year. (And get hammered other years). There are a lot of jobs in the US with companies with fewer than 50 people.
Confiscating the assets of the 1% to create economic prosperity has been tried a few times before, and usually turns out horribly in ten years. You've removed the people who risk their own money from society, and replaced it with only assest allocation by bureaucrats.
Plus, as soon as you removed the one percent, then you have a new one percent.
As much as I like the idea of wealth redistribution I have the same doubts it will work. A similar phenomenon happened in South Africa when it was tried. The initial wealth distribution worked okay but it got rid of owners that knew how to run a business and replaced them with corrupt politicians.
As much as many of the 1% don't deserve it... A lot of them have that much money for a reason. The ones I knew, the "new money", were generally extremely intelligent and hard working before they made their millions. A lot of them are on permanent vacation now but if all of us had that much brains, charm, and grit it would be a lot easier to get rich.
This is what the paper says:
"Total family income is the measuring stick used to determine levels of affluence achieved. This is defined as taxable income of head of household and spouse, taxable income of other family members of the household, and transfer income of head, spouse, and others."
Based on what I know about US tax, you don't have to pay taxes on the first $500k in gains for your primary house (if married), and inheritances usually aren't considered taxable income.
How could there possibly be so many jobs that offer that kind of income. Or maybe it's that most jobs offering high income have short tenure..
