I think UBI would be disastrous for society even if it's perfectly implemented, which in a democracy is nigh impossible because there are too many stakeholders fighting for a piece of the pie. To think that you could replace entrenched welfare schemes with a flat sum sent to each citizen (?) and for it to be relatively successful is a pipe dream. For example, our disastrous healthcare system is a direct result of an afterthought FDR-era program. There are simply too many negative externalities to consider.
You don't need to reinvent the wheel in order to "fix" capitalism. Our current problem is that the 1% are taking too much of the pie for themselves. This has led to increased corporatization, reduction in competition as companies merge and there's less players in any particular field, this results in the white-collar service class being beholden to their corporations, making it unable for them to save enough money to spin off and start their own small and medium sized businesses which would create more jobs for people lower on the economic rungs of society. In effect capitalism is working a little too well/efficiently as the owners of capital are using their entrenched power to squeeze more production/efficiency out of employees, which forces employees to stay employees instead of business owners.
This problem can be fixed by tweaking the tax code and some other small changes at the federal level. You don't need to effectively reboot the system to make capitalism work again for the 99%.
