Are taxes in our country on the lower side?

I was having a meal with a fellow club member just now, and
the topic of taxes came up.
They got all worked up and angry, saying that taxes on the wealthy are too low compared to developed nations.
They argued that it's right to collect more taxes from the rich, similar to developed countries, and that with that money,
we should provide more livelihood support funds
and implement basic income sooner.
I had such a hard time swallowing my food.
I naturally changed the subject and didn't talk about it any further.
The thing is, they don't realize that I faithfully pay 200 million KRW in global income tax and 100 million KRW in the four major insurances (quasi-taxes),
and that I'm not paying 48–50%, but actually around 60% in total taxes,
plus Comprehensive Real Estate Tax ㅠㅠ more taxes...
They don't know how much of a reality check I get every time I pay taxes.
And then there's gift and inheritance tax, where the government takes another 50% at the very end.
I personally believe that high-income earners in our country pay some of the highest taxes,
so hearing that while eating just made me laugh.
As far as I know, in Japan, even middle- and low-income earners pay a significant amount of tax as well.
