Failure to appropriately tax wealth while taxing income alone is the fundamental cause of labour having no value in the modern economic system
Linked proposal would have 0 employment income taxes up to $100k, and 0 payroll taxes. 5% increment surtaxes on sliding scale incomes above $100k. Investment income would have base 25% tax. Taxing the income that is derived from wealth (investments) at equal rate to employment income (the 0 income tax is a gimmick based on not deducting employment expenses from employer) is both the right fairness balance, and high revenue raiser. The far greater benefit to 90% of population, overlapping the employee class, is freedom dividends. Over $36k/year in US per adult can be afforded when we stop thinking of just wealth taxes to fund a larger nazi empire by the oligarchs for the oligarchs.
Taxing investment income is a fools errand because there are a million ways for them to enrich themselves off their holdings without appearing to HAVE income, on paper.
The one big way is borrowing against investments. A $1m-$5m limit would go a long way to eliminating the loophole for ultra rich. Trusts can be taxed more. The loopholes can be fixed.
The race to the bottom in US, is based on piecemeal "populist emotional" local measures, that just as Corporate investments shop arround for biggest local tax breaks, threats of leaving when "fair tax local" proposals/policy pass is a weak attempt at not fixing anything.
Instead of taxing wealth as a principle, I do support financially zeroing out those who sponsor speech of nazi economic fraud, and zionazi theft of American prosperity. But, essentially, everyone is/should be encouraged to get as rich as they want as long as they STFU and pay their taxes instead of corrupting government to make them richer.
