after you say this

Private property is not someone else’s personal property...

you say they are this

...are owned and controlled by investors.

that stuff is the investors personal property (or the corporations but that is a technicality) and them selling it to me is fine as long as there is meaningful competition and no monopolies and govt regulations stopping them from putting toxins in it or something. I dont think the best solution to high prices and wealth inequality is taking the personal property away from these investors and handing it to their employees (who lets be honest probably don't know much about economics) who aren't motivated to take risks with the company and aren't motivated to lower their wages when the company needs to save money or isn't production much money. This lowers the competitiveness of the company, but having a CEO to manage all this while being kept in check with a union is a fine solution to this.

If there is a wealth gap higher taxes on the wealthy is all that is really needed to even it out

Without capital new factories wont be built btw, unless you have a bank or investor financing them. And I don't think bank tellers should get a say in what the bank invests in (if its run by the workers this would happen, as the bank teller is a worker at the bank), because they very probably don't know about the finances and economics of the industry the bank is investing in and wouldn't have an educated opinion on the matter. I would rather have investors (who may have more money than others, but if its too much taxes can fix that, not funky ownership stuff needed) picking small companies, giving them money and later getting back their money as the small companies grow.
