It's only a problem if you think there are a class of people who should not contribute any amount to reviving this country.
No. Did you read what I said? I said it's a problem for people who have spent their entire life paying more than their share of a high rate of income tax.
You and others who try to make this case, tend to ignore the hidden taxes they'd already be paying that are baked into current prices for goods and services. While those taxes will become visible, the consumers may not really pay more in total.
I'm not ignoring anything. Those hidden taxes on goods and services would be less than the visible 9% sales tax.
You're ignoring what I said. I didn't say that the consumer on average would pay more. I said the people who have shouldered the burden of paying taxes would get taxed again when they retire as they spend their savings.
