LSE Research Finds Wealthy Tax Cuts Do Not Benefit Broader Economy

·1 views

A 2023 study from the London School of Economics examined the economic impact of tax cuts directed at wealthy individuals. The research challenged the concept of trickle-down economics, which holds that benefits given to high earners eventually flow down to the wider population. Findings indicated that such tax cuts primarily benefit the rich rather than stimulating broader economic growth. The study contributed to ongoing academic and policy debates about the effectiveness and fairness of top-income tax reduction strategies.

Rust API Design: When to Use Borrowed Data, Cow Type, and Safe Destructors

A technical guide on advanced Rust API design explores the trade-offs between storing owned data versus references, advising that ownership should be required only when the code genuinely needs it. The Cow (Clone-on-Write) type is highlighted as a solution for cases where ownership requirements are only known at runtime, allowing functions to borrow data when no modification is needed and clone it only when mutation is required. Small primitive types like i32 and bool are treated as exceptions, where copying is as cheap as referencing, while large types such as fixed-size arrays should still be passed by reference. The guide also addresses destructors via the Drop trait, noting they are typically expected to be non-blocking and infallible, though exceptions exist when releasing certain resources. Practical code examples illustrate how Cow can be used in function signatures to avoid unnecessary heap allocations.

Go vs Ruby: How Go Replaces All Loop Constructs With a Single 'for'

A developer documenting their transition from Ruby to Go highlights how Go consolidates all looping patterns into a single 'for' construct, replacing Ruby's multiple options like 'while', 'until', 'loop do', and '.each'. Go's conditional syntax mirrors Ruby's logic but uses curly braces instead of 'end' to define blocks. The language also supports 'break' and 'continue' keywords familiar to Ruby developers, mapped to Ruby's 'break' and 'next'. Go's 'switch' statement differs notably in that it does not fall through by default, requiring an explicit 'fallthrough' keyword to continue into the next case. The article concludes that while the two languages differ in syntax and design choices, neither approach is inherently superior — they simply reflect different priorities.
