Yes. Yes you did, by nature of what you said and what it was in response to, which is very specifically a case were taxes raised by 500% over 10 years.
> Taxes usually increase.
A ridiculous proposition on it's face, as it would mean over times taxes always get higher. In the United States, Federal income taxes have fluctuated up as high as above 90% over the last one hundred years. It's not that high anymore, so taxes have gone down.[1][2] The UK has similarly seem fluctuations over time, and it's not currently at the highest it's been seen.[3]
> Do your own research.
If you're going to make an assertion, the onus is on you to back it up.
That said, you should be careful what you wish for, because someone might just take you up one it.
