I don't think a planned economy can be good. East Germany had a planned economy when it was managed by the soviets and we are still recovering from that.
The problem with our current economy is not capitalism per se but more neoliberalism. Neoliberalism is what has allowed megacorps like Google and Amazon to exist and to take massive influence in politics. The free market needs to be regulated, businesses shoudn't have as much influence on politics and there should be more social programs to help the weak.
While it is easy to hate capitalism and seek for other ideologies it will end up creating more harm. I don't know if the current system is fixable or if we would need to overthrow the gouvernment to bring meaningful change but it currently looks like the latter is needed.
