Businesses are a mix of a bunch of things at once: organizations that provide employment (and so, wages, that people need to live + taxes to the government + spending power for downstream businesses), organizations that pay taxes to the government directly, assets that generate returns to owners, productive capacity for goods (some are essential, some are not, and some are essential for national security), centers of research and development (powering innovation that may improve people's lives), social associations (providing structure and community to the people that work there), culturally relevant institutions (think a locally famous restaurant or factory - Katz's Deli or Tennessee Whiskey) and many more.
So, when a politician wants to pass a bill to help certain businesses, you have to ask which of these are they SAYING they want to improve, and which of these they ACTUALLY improve. If you pass a bill that reduces taxes for capital gains, it's usually proposed as a way to produce more jobs (more capital available for investment), but it may mostly be adding to the returns one enjoys from ownership (in an economy where capital is abundant.) The opposite might be true if the economy is capital-starved.
As far as businesses go, land-ownership and management is clearly rent-seeking, and an unproductive use of capital. Human society doesn't gain new products or services or save labor by the mere increase of land prices. If anything, as we see with the homelessness crisis, it can be totally counterproductive. Using my rubric above, landlords aren't providing many of the benefits of a business (no R&D, not many jobs), so they should be lower on the ladder of businesses worth saving. I would much rather support the bailout of a restaurant with a long history than a landlord.
After all, if returns the fruits of risk taking, losses must be the fruits of losing those bets.
