No they aren't. The number that's increasing is a price tag, not cash. That's why no one's wallet or bank account gets bigger when that same number goes down.
Who do you think the profit of increasing the price tag goes to? The workers in the factory to help them deal with inflation, or the rich shareholders?
borrow against those assets to access their wealth tax-free.
...until they pay the loan back, you mean.
Hell, loans better be tax free, it's not income if you have to pay it back.
P.S. Some food for thought: if workers' labor is being 'skimmed' by employers, making workers into a source of profit as a result, then why would a company ever downsize as a measure against financial difficulty? Why would any business ever fire anyone who's doing their job, if worker = profit for the business?
