Luckily, you get a nice discount if you can stay out of the currency long term and qualify for long term capital gains.

Basically, currency inflation is very well designed to suck value out of the poor and working class while the rich have plenty of breathing room to float through the flood.

In Romania where I live, there is no such exemption.

Whether that's good or bad for rich or poor people, I have no idea. But I assume keeping your money invested for a long time is harder when poor.

Then again, plenty of reasonable assumptions have been proven wrong by behavioral economics.

Inflation is a tax on savings, but the poor don't have savings by definition so... I think you need to think a little harder.
