There are quite a number of solutions on offer - they just have a difficult time gaining traction in our media (and therefor in the public debate). Part of that has to do with the fact that a majority of those with economic and political power - those who have succeeded in the current system - still refuse to recognize that the problems are systematic. They refuse to recognize that the problems are intrinsically caused by our economic and political systems and necessitate systematic change to those systems. And since these people wield economic and political power, they have the ability to prevent the conversations about these problems and their solutions from being held in the halls of media and power. Thus, the solutions are only discussed among fairly niche political and academic communities who have a hard time broadcasting the ideas widely.

But if you go looking for it, there is a wide array of work that has been done divising ideas for the systematic change we need to solve these problems. I have a whole bookshelf of authors proposing alternatives. Projects like The Next System project, and the Democracy Collaborate, have been working on divising ways to grow alternative systems with in the confines of the current one.

The challenge of course, remains funding. Because those with the wealth got that wealth through the current system and continue to benefit from the current system.

So actually making change is going to take either a mass popular uprising (electoral or otherwise) or enough people with enough wealth recognizing the problems and being willing to give up their wealth and power to solve them. Knowing that the solutions will forever disempower them and their peers.

Edit:

To provide some clarity of the sort of solutions on offer, I'll provide my favorite. Stop prioritizing capital, start prioritizing labor. Right now, Capital basically gets to call the shots - because we allow for any kind of contract in business formation and you can't start a business with out capital and we don't restrict what capital can demand. This allows capital to take advantage of that power imbalance at the time of business formation to demand control. If instead, we restricted what capital could demand to say - a reasonable interest on a loan - and legally structured businesses as institutions democratically run by those working in them, this would have the effect of empowering labor and disempowering capital.

People would still have the ability to make money from their money, but it would vastly reduce the current multiplier effects on the growth of wealth, and thus the tendency for wealth to concentrate. It would tend to spread wealth out to a much wider proportion of the population - because the people doing the work would get to vote for the leaders of their businesses, and those leaders then have a much, much strong incentive to take care of the people doing the work. Likewise, the people doing the work would have a much stronger incentive to take care of the communities in which they operate, because they are much more likely to live in those communities than distant investors. It has the effect of reconnecting businesses with their neighbors and communities in a much more real way, and empowering those involved in the business who are most aware of the effects it has to change those effects.

Would this system be perfect? Nope. It's really a pretty gentle refactor of the current sytem (though one with wide ranging effects). Would it be better? Yeah, I really believe it would.

There are many other effects this change would have - I've wanted to write a book on it for years, but haven't been able to find the time or bandwidth. Someday. If I ever get to take a long leave of absence or get to cash out, someday.

Another alternative you could consider, one I've played with as a thought experiment many times, what would happen if we simply banned people from making money directly from their money in all forms? It's a challenging thought experiment, because where do you draw the line? Money is just a representation of property, so how do you define money made from money versus, say, renting a machine you own? But it's a worthwhile thought experiment - could we devise a system where you could only make money by working, and not by simply owning property or holding wealth?

There are many more alternatives out there, from gentle refactors to whole rewrites. Some fleshed out, some just thought experiments. And everything in between. They should really - all of them - be a much bigger part of our public dialog than they are.

Further edit: Many threads are on-going but I've been at this all morning so I'm going to call it a day and go make lunch. I've appreciated the dialogs, and maybe I'll write that book some day. If I do find the time to write that book, I know exactly where to come to harden it against criticism. If I can convince a forum full of capital investors and would be capital investors that making capital investment illegal is a good idea, then I'll be able to convince anyone!
