> Assuming the tax rate is 50%
Which is not(?). According to https://en.wikipedia.org/wiki/Corporate_tax_in_the_United_St... , federal corporate income tax rate is 21%, + additional <10% for state level, not sure about local level.
Note that LLC isn't a tax status
An LLC can either file as a c corp and get corporate tax rates, or (sometimes) file as passthrough like as in a sole proprietorship. Or as a partnership. It gets complicated

Anyways, it's up to you, it's not necessarily due to it being an LLC.
One of the reasons small businesses have been hit so hard with this is because for then (when incorporated as LLCs), their tax rate is 37% + state + local. I live in NYC and my LLC has a combined tax rate of 50%.
