Hey Hobo, leaving ethics aside, I think you got your answer a plenty.
PS: Alot of folks go into biz for themselves after working in or learning a trade by working for someone else. What better way to build your business on than something you know, right? lol. Some folks here work for others while conducting a side biz for themselves. Sometimes young businesses just can't fully support a household, so there has to be that main gig $ to keep things afloat. Doing side jobs crosses many industries, from shirts, to construction, to computer networking, and so on, I think we all see it all around us. I wouldn't worry about anything like that.
As far as taxes are concerned, and your intentions toward taxes in particular, the first thing you said was you plan to pay your taxes, not that it's any of my business, is how I feel about it.
I hope folks pay their taxes, it helps relieve the burden shared by all of us to support the country. The more who pay in, the easier the burden on all of us (lol, or the more money they toss around pitifully lol). But, honestly, to me, just like your personal business, how you run your business is also not my business or my place to judge. So as for you explaining yourself, I can't help feel it's just not needed -- if you ask me.
Besides, I think folks aren't talking about You paying your taxes, I think they are saying those companies assist people in not paying taxes. But I think people who don't want to pay taxes don't need any assistance, they can figure out how to do it just fine without Alpha or the others on that list. Just my 2 cents.. again -- so that must be 4 cents... making this an expensive thread for me!

Peace to all!
We can't change the world, we can only change ourselves. Make it a better place one person at a time, starting with you.
