Doing the minimum that you legally have to is not "paying it forward"...
Says you, I have pride in paying taxes.
I think some nuance should be in order. After all... Some people pay say 10% while others pay say 45-50%.
I live in Sweden. Taxes are... high.
If you work a stressful job and pay more taxes than the average person, then arguably you are doing more than the "legal minimum".
In some more socialist countries, the "legal minimum" is choosing to live off welfare and not working/paying taxes at all.
Assuming you live in a democracy, I guess this goes alongside "I vote for higher/more progressive taxation or fairer redistributive policies whenever I can."
