I can't follow any of this. I'm not sure how moving some place, getting an apartment, getting a job, paying taxes, etc. (aka "living") constitutes "mooching and freeloading". I think you need to take Rhetoric 101 again.
Let me explain what you don't understand and can't follow. The massive influx of people into Austin has degraded what Austin was because it has exceeded any capacity to fully absorb them without a degradation. When you arrive at something that others built and paid for and yet still have full access to as if you had paid for it, that's when you are mooching and freeloading specifically. That's the whole definition of freeloading, not paying for something that you are using or taking advantage of.
Now that you are provided with the information to understand what you could previously not, let me further help by illustrating the only way in which it could not be freeloading and mooching. If new comers had to pay exponentially higher tax rates, essentially as a kind of compensation and even a rate of return, which in turn then lowered the taxes of locals that would be the only way to not be freeloading and mooching, especially in a system like Austin that is in no way capable of sustaining the influx of people without significant impact and degradation of the very thing that attracted the freeloading and mooching types.
You seem to be under the impression that somehow paying the cost of operation is sufficient to compensate for prior investments, let alone rates of return. It's quite ironic that such an erroneous mindset would exist in this forum. Then again, it is a tech startup forum, so it really isn't all that surprising.
Think of it this way. If you take n amount of money and invest it in starting a company by buying facilities, equipment, various other capital goods, and hire people; how long to you think you would last by selling your product or goods at the cost of variable inputs alone? ... not even to mention the return on capital or investment. And that still doesn't even get close to capturing the human factor of community and society and culture that is lost through such a destructive locust like swarming of places.
I get that most people in here can't think past their own selfish wants and desires, but what do you think makes a place, any place, so attractive so that you want to go there, it's not your contribution that you made to that place. You are a textbook freeloader at that point, especially in smaller places like Austin used to be where all the things that attracted people to Austin like community and culture existed before they smothered it.
We are going to see ever more of these kinds of things happen as the internet causes human swarming behaviors. Maybe one day people will start realizing it and its absolutely detrimental impact on society and humanity. It is in effect a great leveling and averaging of humanity, a regression to mediocre mean that destroys uniqueness, actual diversity, and civilization, and incentive for community and creation. What are we when there is nothing unique anymore because the second something becomes great and a community comes together, an influx of freeloaders that want to mooch off of it start pulling it down? We are facing a future of the commoditization of humanity, accelerated by the internet and the exponential pace at which anything good or unique is discovered and immediately smothered and trampled.
Did you build Austin? What constitutes a "local"? No one anywhere in America (or anywhere on Earth that I'm aware of) is required to pay a "foreigner tax" for moving into another city within the same country, which they are already a citizen of. Everything is supply and demand, everything is a push and pull. If Austin is bursting at the seams, it will take a few years for investment and policies to relax it. If Austin starts to empty out, slowly the city will shrink. The ebbs and flows of change are always happening, nothing is constant, everything is in motion. Austin is better served by attracting people than it is by pushing people away.
I was born in Austin, and I've lived here for about eight years. This city and it's people have taught me so much, and I really don't know who I'd be if I never came here. I want to share this place with as many people who want it. If you like what you've heard, come join us. We have a bit of a housing shortage that's driving up the cost of housing, but that's okay. We'll just build more homes.
