Will the government impose a wealth tax to raise capital?

[Bjauck]

"All gains, income and capital, should be taxed"

So along with that I presume you think all capital losses should be deductible.

"All gains, income and capital, should be taxed"

Then it would no longer be a flat tax.

All net gains...so yes losses would be deductible or be able to be carried forward...

Of course it would still be a flat tax if all gains were taxed at say 20%. It is an arbitrary decision to tax all income and not all capital gains.

However you may be talking about a poll tax? Every person (or adult?) taxed the same dollar amount? Which of course takes no account of career progression and would end up with a gerontocracy with most young adults and families in tenements owned by the one percenters?
