There is a mentality of greed, @David S. that I believe exists and I tire easily of hearing of the exploits of the Donald Trumps in the world. There is NO social consciousness there and the "socialist" part of me thinks that when, whether through your own efforts or dumb luck and good fortune you are blessed with much, then you should be giving back. It's the how you give back and to whom that I and probably 95% of others would have different views on. Personally, I think that for most of us in the investing world, the road to the first 10-20 doors will be marked with a great deal of blood, sweat and tears. Those doors will be EARNED. There is nothing about the work done though that couldn't be done by anyone else IF they wanted it and IF they applied themselves. The information is out there. Right here, in fact, on this very forum. I would be proud to say I had worked hard enough and long enough to own 10,000 or even 210,000 doors, especially if it meant that I could honestly say that the tenants of those doors were getting a good quality living space for a reasonable price. There wouldn't be any greed involved. That volume of investment done right would enable a tremendous ability to give back in so many ways that a "mere" 100 or 500 doors would not.
When all the money rests in too few hands, its a bad thing for everyone in my opinion. What is too few though is a hard one to answer. It's more the caliber of the individuals possessing the money than the amount of money possessed. I used to think that Bill Gates was too rich. He kept getting wealthier and his business kept getting even more of the market share. Seemed like everyone had to use Microsoft. And he never contributed to any charities to speak of. That "socialist" part of me was irritated. Then he got closer to retiring and being able to fulfill his dream, married Melinda and together they created the Bill and Melinda Gates Foundation. His vision was not just to give incredible amounts of money to charity, but to raise the standard of education worldwide and in doing so enable so many to do things for themselves. He had had a dedicated and focused plan all along! Since then he has convinced the very richest of the rich to give away their fortunes. He has become an ambassador of spreading the wealth. Have you read the news recently about Warren Buffet? He was one of the first ones that Bill Gates got to join him on that bandwagon and he has given away tens of BILLIONS of his fortune already. And there are literally dozens more that have pledged to do the same.
Each and every one of the people giving away fortunes had at one time or another, I'm sure been one of those with "too many doors". I am thankful that there is great wealth that still can be created, be it through investing in real estate or otherwise, and for those, apparently like yourself, that have a little "socialist" in them and a concern for making it just a little easier and better for others. I am praying that you become one of those with WAY too many doors, and that you find a way to use the wealth. Rock on!!
