Universal basic income reduces buerocracy, as it reduces the number of management required by classical welfare systems. It also increases freedom and enterpreneurship because it allows people to pursue their passion projects. Where's the freedom in having to wash plates to side fund your startup or pay of your giant student loan?

The reason why our tax systems are so bloated with bueraucracy is because neoliberalism has been pushing for tax breaks of the ultra wealthy for decades, which results in an increased tax burden on the middle and lower class. Since you can't tax those easily without risking stalling the economy you have to create these elaborate taxation schemes.

If you want to reduce bueraucracy start lobyying for a bracketed tax system that reduces the total tax rate for households up to 1 million per year and a quadratically increasing tax rate to 100% at 100 million. Include stock transactions in those numbers, and you might even have a decent chance at returning the stock exchanges back into a kickstarter like system of funding and rewards, instead of the grotesque casino like playground for HFT algorithms that it has become. At the same time abolish all other taxes. You should probably reuntroduce a pollution tax, to prevent companies profiting from externalising their costs, and frankly if we want some shot at climate change we need to introduce some incentive to not pollute the living hell out of our planet, and not dying in a 60C heatwave, flodding, tornadoes, or refugee crisis is apparently not incentive enough.

Less people taxed with less forms of tax means less management required. The walthier the people taxed, the less they are incovenienced by the tax.

Trickle down economy didn't work, and "but if people can't earn billions per year they won't work anymore" is a joke. It's time we structure our society around enterpreneuship, hard work and passion, instead of giving all the power to people that are a statistical artifact of an exponential reward system. Multi billionaire are a bug in capitalism not a feature, and you are not a temporarily embarrased billionair.

Fablabs are a good example of communized production. These should be state funded, just like schools are, combined with UBI, it'd give you the resources to tinker and experiment and a community for others to partake in that process. Less bueraucracy, less government, less involved state and politicians, yet more social, more community, more freedom.
